      The MERIT (MeVis Image Registration Toolkit) module is a software framework for image registration. It is particularly aimed at the rapid prototyping of registration methods often required in everyday work with MeVisLab. Among its core features are:

      • 2-D/3-D affine-linear image transformations (translation, rigid, similarity, rigid+scale, affine) with customizable component orders.

      • Newton-type optimization (and approximation thereof) with line-searching (linear or Armijo's rule).

      • Multi-resolution image pyramids with custom downsampling, stop levels, and number of levels.

      • Inherent pre-registration initialization schemes (e.g., initial matching of centers of gravity).

      • Five common image similarity measures (SSD, NCC, NMI, LCC, NGF).

      • Nearest neighbor, cubic, Lanczos, and linear image interpolation methods.

      • Multi-threading support using OpenMP processor threads.

      • Robust convergence criteria, e.g. Gill-Murray-Wright, for a unified convergence behavior of all algorithms.

      • Entirely graphical usage through a consistent user interface.

      • The float and long double variables have been consolidated to double variables. Legacy mechanisms will keep field connections and expressions working, but usage of the old variable names will produce warnings.

      • Arithmetic will no longer work with images of different extents. Use a SubImage module to adjust sizes of input images.

      • Both modules are now capable of detecting domain errors while calculating and can react according to user settings.

      • Anonymous vectors and vector index operators in Calculator now accept any expression as components and index, respectively.

      • A length function for vector types has been added.

      • Calculator returns scalar results when vectors in the expression evaluate to scalars (for example, length or dot product).

      • Arithmetic can be used as a constant image by providing a type and an extent instead of working on input images.

      • In Arithmetic, expressions can use special variables to access the current voxel position.

      • MLDICOMAccessories available in public sources now.

      • MLDICOMCachedIO (also available in public sources).

      • MLGDCMPrivateDICOMTagDecoders (also available in public sources).

      • MLPrivateDICOMTagDecoders (also available in public sources): allows implementing your own DICOM tags decoders.

      • MLPrivateTags available in public sources now.

      • MLReleaseTools and MLReleaseToolsStable (also available in public sources): collection of C++ tools for string conversions, index list parsers, directory scanning, progress logging, interrupt checking, simple path handling, (sub)image saving, icon generation, file type detection, etc.

Version 2.2 Stable Release (2011-06)

Platform-independent Modifications

  • New Public Sources:

    • There are new FME-modules and projects in the public sources providing efficient implementations of often used standard algorithms, demonstrating some new image processing features of the ML, or allowing for a closer look into the binding of VTK modules to MeVisLab or into the programming of plugins for DirectDicomImport:

      • TensorToEigenSystem (FMEstable project MLTensorToEigensystem)

      • GaussGradient and GaussHessian (FMEwork project MLGaussFilters)

      • ImageCumulativeSum (FMEwork project MLImageCumulativeSum)

      • ImageResample (FMEwork project MLImageResample)

      • QuadraturFilter and QuadraturToTensor (FMEwork project MLQuadratureFilter)

      • TubularTracking (FMEwork project MLTubularTracking)

      • DirectDicomImportIteratorOutput and DirectDicomImportWaveformOutput (FMEwork project MLDirectDicomImportOutputs)

      • FMEwork projects VTKSupport and MLABVTKRenderWidget

    • Additional SDK-Interfaces:

      • Additional DirectDicomImport-headers (FMEwork)

      • MLInternalPageCache (FMEstable)

  • Fixed modules:

    • Fixed MLReplaceDeprecateAPI helper module.

    • VoxelizeInventorScene was not correctly restoring the OpenInventor state. Updated documentation.

    • CSOConvertToImage: values of CSOVoxelSet voxels are now filled with image values if the module should use image values.

    • CSOVoxelSets now retain the voxel-to-world-matrix of the source image that is used in CSOVoxelSetToMarkerList to create correct world marker positions.

    • The GVR renderer used GLSL shader code which caused an ATI driver crash on some ATI cards/drivers. The GLSL shaders have been modified so that the standard GVR slicer shaders used in View3D etc. should work again. The new GVR ray cast shaders and some advanced slicer shaders will still have the problem. Since this is an ATI driver bug, we filed a bug to ATI. Hopefully this will be fixed in a future ATI driver version.

    • View3D: Avoid clipping the annotations.

  • SDK:

    • Fixed Snippets List feature by using a dummy image if no screenshot could be created (e.g. because of an insufficient OpenGL driver).

    • Added a MEVISLAB_VERSION define, current value is 202.

    • Fixed that DynamicFrame control crashes when its content does not contain a GUI control.

    • Fixed a seldom crash under 64 bit versions of MeVisLab that could occur with connections between Open Inventor fields of different types.

    • Fix that module help is not generated for deprecated modules.

    • Various small documentation updates.

  • ADK:

    • Fixed that the ModuleDependencyAnalyzer macro does not find modules with an explicit instance name.

    • The standalone ModuleDependencyAnalyzer tool considers user packages now and can also consider an additional preferences file.

    • Fixes to the StandaloneInstallerWizard.

Windows Edition

  • ADK:

    • Added missing zip.exe.

Linux Edition

  • SDK:

    • Fixed wrapper scripts when used in directories containing spaces.

    • Fixed location of MeVisLabMovieWrapper.

  • ADK:

    • Installer creation requires installjammer version 1.2.14, version 1.2.15 does not work.

Mac OS X Edition

  • SDK:

    • Added initial support for Xcode 4:

      • Xcode 4 does no longer crash while trying to open project files created by qmake on behalf of the MeVisLab Project Generator (QTBUG-17247).

      • The MeVisLab Project Generator creates default Xcode 4 schemes for the Xcode projects. A Debug in MeVisLab scheme is created for MeVisLab module library projects.

  • Documentation:

    • Updated MeVisLab Mac OS X Edition User's Guide

Version 2.2 Release Candidate (2011-05)

Platform-independent Modifications

Fixes/Enhancements (MeVisLab)

  • New Features:

    • We moved to a new internal help file format (.mhelp) for modules which can be edited with the integrated MATE text editor. These are converted on-the-fly to HTML. The old HTML files are deprecated.

    • MATE has been made a separate program which communicates with MeVisLab instances (if available) for auto-completion and other needs.

    • MATE now contains the frontend for a new integrated Python debugger which support breakpoints, stopping on exceptions, call stack and variable introspection.

    • All modules from the MeVisLab/Standard package that still used JavaScript have been ported to Python.

    • MeVisLab does now provide its own Python version (called MeVisPython) for command line use. A separate installation of a Python version is not needed anymore.

    • Profiling has been improved and now contains a call graph view.

    • Implemented some performance optimizations for loading *.mlab files (especially when there are many field connections).

    • Added lazy script evaluation which can be enabled with LazyScripting = true in MeVisLab prefs file (this defers creating the script context until scripting is really used).

    • Added a "Snippets View": fragments from a network can be stored for future usage in a dock in the MeVisLab IDE.

    • Added an option to set module placement style in the IDE.

    • Added a customizable network view mouse interaction.

    • The reloading of selected modules can be triggered by F5/Cmd+Alt+R and has a visual feedback now.

    • Image inputs/outputs can be colored according to state in the network view for diagnostic purposes.

    • Added a preview and navigation feature for internal networks - press Space when no module is selected.

    • Added a context menu entry for modules to check library dependencies (calls DependencyWalker under Windows) for Linux and Mac.

    • MeVisLab now contains the Qt libraries and header files that are needed to implement custom MDL GUI controls and to make use of Qt in MeVisLab modules. It is no longer neccessary to install a separate Qt SDK. Make sure that the QTDIR variable is NOT set in your environment, so that MeVisLab can make use of its internal Qt version.

    • MeVisLab can now be installed at paths containing spaces even if Qt is used.

    • The MeVisResearch package group has been renamed and split. The new names are FMEwork and FMEstable. (MeVis Research is now a Fraunhofer institute.) Users usually should not notice this change.

    • Modules can be aligned with optional tool buttons.

    • Added an option to convert a module group to a (local) macro.

    • Added an attribute 'editable' to fields. This attribute sets the default for the 'edit' or 'editable' of controls representing this field. At the same time it sets the 'persistent' attribute if not explicitly given. Non-editable fields are also not editable in the automatic panel.

    • Added a standalone tool for static module dependency analysis (for application deployment with the ADK add-on).

    • Possibility to execute single ML or macro modules asynchronously in a separate process (with some limitations). This is an experimental feature which needs to be unlocked via the prefs file.

      Limitations:

      • OpenInventor modules/inputs/outputs do not work (but you can use the RemoteRendering module and the RemoteRendering control to do rendering in a remote module).

      • Image outputs work, but image inputs do not; read images from a file instead.

      • Base inputs and outputs work in principle, but need a Base type handler for the remote communication. Currently there exist only handlers for XMarkerLists and some specialized remote helper types.

      • The panel and scripting of a module will only work in remote modules if it does not violate some encapsulation rules.

      • Remote modules are executed asynchronously, so field updates that previously would happen immediately will happen delayed.

  • C++ API Changes:

    • Various changes to the C++ Field/FieldContainer API: ml::Module is derived from ml::FieldContainer now, and some rarely used or ill defined methods have been removed.

    • Those variants of the FieldContainer::add*() methods that take an external data pointer are renamed to FieldContainer::addDeprecated*(). Using these method versions is (and has been for quite some time) strongly discouraged.

    • The regular FieldContainer::addInt/Float/...() methods now have the initial field value as second argument to avoid an extra setInt/Float/...Value call.

    • Base fields can now be restricted to allowed sub-types of class Base (this is used in MeVisLab to do a type check when connecting Base fields).

    • Base fields now support intrusive reference counting via a new RefCountedBase class (but this is not yet used in any modules).

  • Scripting:

    • Module groups and note items in a module network are scriptable now.

    • MLABModule has a hasWindow call now.

    • Added getFrameSpecificDicomTag and getFrameSpecificDicomTagById to MLABImageField.

    • Added storingToUndoHistoryCommand and restoredFromUndoHistoryCommand commands to MDL - modules are now informed when they are moved to/from the undo buffer.

    • MLABImageField::image().getSliceAsQPixmap() and MLABImageField::image().getSliceAsQImage() allow to get a QPixmap/QImage from RGB and RGBA ML images. These images can then be used on MDL controls (e.g. MLABButtonControl::setPixmap()) or directly on the Qt API.

      • Access to driver-specific functions is provided via base-field access.

      • New SoVideoCaptureSampler2D module that uses a driver-specific function to provide access to the video frame in GLSL code (see SoShader modules).

    • New VideoLoad module to load video files, the supported formats depend on the platform-specific backends used by OpenCV.

    • New SoSimulateMouse module to simulate mouse interaction via scripting or network.

    • New View2DTouch macro that offers additional interaction capabilities using gestures, an image dataset my be explored from the trackpad of modern notebooks or by using an external trackpad like the Apple Magic Trackpad.

      • New modules SoTouchpadDevice, SoView2DTouchControl, SoSwipeAccess.

    • New modules: CurveSelect (selects curves from a CurveList), CurveImport (creates CurveData from ascii text).

  • Other ML Modules:

    • The ConnectedComponent module has been reworked.

    • The MergeRegions module now allows to deactivate auto-update.

    • Added the ImageClear module, which automatically invalidates its output on input image changes - the user has to "manually" pass the input image through. This can reduce notifications.

      • New plugin mechanism available (see DirectDicomImportImportFilterPlugin) for filtering and classifying DICOM files before importing them.

      • New DirectDicomImportIteratorOutput module for iterating over volumes.

      • Radio-Therapy modules are also available on Linux platform now.

      • The eatDicom importer in DirectDicomImport has been removed, which leads to a number of "missing field" messages when reloading network built with older versions. Please resave those networks.

      • Many fixes, especially in voxel size and matrix calculations.

      • Many new features, such as sorting according to DICOM tags, additional import directories, experimental waveform output.

    • LocalImage has been changed to return a new dataset by default that has anisotropic voxel size, is sagittal, has DICOM tags and does not have equal image extents.

    • ModifyRegion refactored to support non-CT world/voxel matrices (e.g. from MRI)

  • Controls:

    • New MDL controls RadioButtonGroup, PushButtonGroup, ToolButtonGroup that shall replace the ButtonBar control.

  • Added support for Visual Studio 2010.

Linux Edition

  • MeVisLab is now compiled with gcc version 4.4.

  • Added support for DICOM RT.

  • Library symbols are now exported explicitly under Linux; this should reduce library sizes.

  • The mlbash script in <installpath>/bin has been renamed to mlshell to reflect that other shells than the bash can be used. The environment variable SHELL can be set to specify a shell. If it is not set, then the bash is the default.

  • The prefix or infix MLAB was added to most third party libraries to avoid the MeVisLab loads same named, incompatible system libraries (e.g. libQtCore.so is now called libQtCoreMLAB.so, libfreetype.so is now libMLABfreetype.so).

  • The compiler defines linux and Linux have been removed, so that only the define LINUX remains.

  • Added include paths to generated Codeblocks projects to allow more code completion.

  • New tool MeVisLabDependencyViewer: requires the unix tools nm, ldd and readelf. It can be started from the context menu of a module in MeVisLab (Debugging -> Show DLL Dependency).

  • MeVisLab now tries to use the system fonts DejaVuSerif.ttf and FreeSerif.ttf for OpenGL font rendering if they can be found. Otherwise the not so nice font AntykwaTorunska-Regular.ttf is used as a fallback (this font is shipped with MeVisLab and was always used until now).

Version 2.1 Release Candidate (2010-06-04)

New Features

  • TestCenter/TestCaseManager

    • The MeVisLab Tester has been replaced by a new testing framework that is based on Python.

    • A TestCase consists of a Python script and a MeVisLab network that should be tested.

    • Each MeVisLab package may contain TestCases, which are managed in the TestCaseManager.

    • A simple ASSERT/EXPECT_EQ/NE/TRUE/FALSE API offers quick test writing.

    • Various other features, e.g., creation of screenshots and attachment of result files to the test report.

  • ML BackgroundTasks

    • The new library MLBackgroundTasks adds support for asynchronous image processing to MeVisLab.

    • New example modules: AsyncProcessAllPages, AsyncTypedProcessAllPages, AsyncTileProcessingExample and AdvancedBackgroundTaskExample.

    • ImageSave and GVRVolumeSave now support asynchronous writing ("Save in Background" buttons).

    • The MeVisLab IDE contains a new BackgroundTasks inspector which shows running background tasks.

    • For more details, have a look at the "ML Tool Box Reference", which contains the detailed API documentation.

  • MeVisLab Profiling

    • MeVisLab contains a new Profiling Inspector

    • Profiling measures:

      • time spent on ML image processing and field notifications.

      • memory usage of ML modules

      • number of field notifications

  • GVR Shader Pipeline

    • The GLSL shaders used by the GVR are now extensible using the SoGVRShaderFunction module. When this module is used, the shaders are built as a pipeline of GLSL functions. The user can add custom functions, and replace existing functions.

    • New modules: SoGVRShaderFunction, SoGVRShaderInclude, SoGVRShaderPipelineInspector

Common Enhancements / Fixes (MeVisLab)

  • ML:

    • The ML C++ API has been renovated and large portions have been marked as deprecated. The "ML Reference" contains a list of all deprecated functions/classes and a short introduction on the deprecation. Common abbreviations have been expanded e.g., getImgExt() is now called getImageExtent().

    • A new MeVisLab module called MLReplaceDeprecatedAPI has been added, which can be used to find and replace usage of the deprecated classes/functions.

    • Use DEFINES += ML_WARN_DEPRECATED in your profiles to enable compiler warnings about usage of deprecated APIs.

    • Use DEFINES += ML_DISABLE_DEPRECATED in your profiles to completely disable the deprecated APIs.

    • The deprecated API will stay part of the ML API for at least 2 years.

    • The image processing in an ML Module can now be implemented in an extra handler derived from CalculateOutputImageHandler, which is useful to separate the processing function from the module state, especially when multithreading support is desired.

    • CalculateOutputImageHandler is extended by TypedCalculateOutputImageHandler<> templates to support templated handlers.

    • processAllPages now supports a ProcessAllPages handler, this avoids the need to reuse the calculateOutputSubImage method of the ml::Module for processAllPages.

    • processAllPages now calls calculateOutputImageProperties() with the temporary output image, thus the user can specify the properties of the temporary output image, e.g., set the page extent or the datatypes of input sub images.

    • The bypassing mechanism of the ML has been rewritten and now works across multiple bypassed modules and for memory images.

    • ModulehandleInput supports a new enum ALLOW_INVALID_INPUT, which removes the need to use REDIRECT_TO_DUMMYOP, which has been deprecated. See the ML Guide for details.

    • ml::PagedImage now supports sparse page tables larger than 2^31 pages, thus the ML now supports very large images.

    • ml::PlaneField and ml::RotationField have been moved from MLTools to the core ML and are now available on ml::FieldContainer via addPlane() and addRotation().

    • MLLinearAlgebra now contains ml::Rotation, ml::Plane and ml::Line.

    • ml::SubImage now contains the source image extent and knows its valid region (see getSourceImageExtent() and getValidRegion().

    • ml::SubImage now supports caching via the new method ml::SubImageallocateAsMemoryBlockHandle().

    • New ml::TypeTraits<> class offers easy access to compile-time information on ML datatypes.

    • New ml::PageIDIterator class allows to incrementally calculate page ids in a given region.

    • New mlWarning(), mlError(), mlFatalError() macros have been added which support streaming additional information into them and are nicer to use than ML_WARNING, ML_ERROR macros.

    • Methods like getTile(), updateImageProperties(),... that took a module and an output index now take a PagedImage, which is less error prone (deprecated old methods are still available).

    • The preferences variable MLCacheSize is now called MLCacheSizeInMB. You may need to adapt this variable in your mevislab.prefs file if you used MLCacheSize before (the value to MLCacheSize had been in KB).

    • Some incorrect operations/results in MLHolds/MLRangeOrder and MLPromotedType where fixed.

    • Incorrect identification of all floating point vector voxels as double voxels fixed.

    • MLuint64 voxel type introduced to all ML classes, macros and switches as well as in the modules.

    • ToolsscanInput function of MLTools now also analyzes all components of non scalar voxels. This fixes incorrect min/max values in MinMaxScan and Scale modules when using real min/max values.

    • The former TVector/Vector class (now named ImageVector) has been revised and supports n-dimensional vectors now.

    • The integer voxel types Vector16, Vector, and Vector64 have been removed. Now they are provided as 8, 16, 32, and 64 bit versions for the dimensions 2,3,4,5,6,7,8,9,10,16,32, and 64 as for the floating point voxel types, too.

  • Open Inventor:

    • Input devices derived from SoQtDevice are now registered to the run-time type system, hence can be created via run-time type system (see Inventor/Qt/devices/SoQtSubDevice.h).

  • MDL:

    • The list view control (MLABListViewControl) has been re-implemented, which e.g., allows to

      • set foreground and background color and font attributes on list view items

      • store a user data object on list items

      • use a combo box when editing list cells

    • New ButtonBox control, which presents Button controls in a layout that is appropriate for the operating system's look & feel. The order in which the child Buttons appear depends on the window system.

    • Added role attribute to Button control that specifies the buttons role within the dialog and is used by the ButtonBox control

    • Fields can now be connected even if they are disabled

    • New MDL tags styleSheetString and styleSheetFile to set the Qt stylesheet for any MDL control recursively

    • The MDL attributes bgOrigin and ignoreMinSize have become obsolete

    • Labels can now contain unicode characters with codes >= 256 (provided the file contains the correct header for UTF8 encoding)

    • New WebView MDL control integrates a full WebKit based browser engine into the MDL (see TestWebView for examples)

    • The MDL offers a new interface to extend the MDL with user MDL controls written in Qt/C++. This requires a Qt 4.6.2 SDK installation which is publicly available from Nokia. Have a look at the ColorChooserExampleControlTest and DiagramExampleControlTest module.

    • Label control now supports HTML hyper links via new tags allowLinks and linkActivatedCommand/linkHoveredCommand

    • The line edit control can show a hint text if it is empty and doesn't have focus.

  • Scripting:

    • Python scripting has been upgraded to version 2.6.4 .

    • PythonQt binding has been upgraded to PythonQt 2.0

    • NumPy is now included in the Python distribution that comes with MeVisLab.

    • MeVisLab now offers complete access to the Qt libraries in Python, have a look at the MeVisLab Scripting Reference for details. This is an experimental feature.

    • Python C Extensions (*.pyd/*.so) are now supported anywhere (it is no longer required to place them in Package/lib/python), so you can place them to Package/Modules/Scripts/python as you would do with *.py files.

    • MLABImageFieldimage() offers a new API to the underlying ML image, including requesting image data via getTile() to do image processing in Python.

    • It is now possible to implement ML image processing modules in Python. Search for Python* in the quick search to see some examples.

    • New scripting classes MLABDicomTree and MLABDicomTag. MLABDicomTree is returned by MLABImageFieldgetDicomTree().

    • File dialog boxes now remember the last selected directory persistently

    • MLAB.mdlControlAtGlobalPosition() and MLAB.mdlControlAtCurrentCursorPosition() added to find an MDL control from a global screen position or the current cursor position.

    • Added classes to handle field-value test cases, that allow applying a parameterization to a network, verifing expected results and saving specified field values.

  • IDE

    • A new quick search in network has been added (CTRL-F on the network), which allows to quickly find modules, fields and associated files.

    • A lot of network rendering improvements.

    • "Debug Output" inspector now supports exploring the containing folder of a file via holding CTRL key while clicking on a file link

    • Note items will now display non-ASCII characters in the network.

    • The IDE partly relied on the Qt3Support library from Qt. The remaining parts have been rewritten so that MeVisLab solely relies on Qt4.

    • "Extras->Reload Imported Python Modules" reloads all imported Python modules, which previously required a manual reload() call or a restart of MeVisLab.

  • Packages

    • Packages now support a lib/release and lib/debug directory, which is placed into the PATH depending on the version of MeVisLab that is started (Release/Debug), this allows to place thirdparty DLLs into release/debug dirs if both debug/release DLLs use the same name

  • Tools

    • added -prefs, -ignoreprefs and -scanpath commandline options to ToolRunner

    • added -prefs and -ignoreprefs commandline options to MeVisLabPackageScanner

Incompatible changes

  • MLLinearAlgebra

    • TVector<> cannot be used as 6D vector any more, it has to be replaced with TImageVector<>.

    • Some constructors of ImageVector (the former Vector/TVector<> class) do not implicitly cast integer or differently types vectors any more, because this had many undesired side effects. These constructors must explicitly be cast now, i.e. instead of ImageVector v=17; use ImageVector v=ImageVector(17); now.

  • ML

    • ml::Module::calcInSubImgProps has been removed and needs to be manually replaced by calls to ml::PagedImage::setInputSubImage*() calls on the output image in calculateOutputImageProperties().

    • ml::Module::connectInput() has been removed, replace it by using handleInput().

    • ml::SubImage is no longer derived from ml::ImageProperties.

    • ml::SubImage/ml::ImageProperties no longer have an isUpToDate flag.

    • ml::SubImage no longer stores min/max voxel values, you may get those value via getInputImage(N).getMin/MaxVoxelValue().

    • ml::Host/Module::processAllPages no longer takes two leading integer arguments, the second argument (the input image properties that should be used for the output image) has been removed and can be replaced by code in calculateOutputImageProperties() if it wasn't set to 0.

    • ml::Field::attachField(targetField) is no longer allowed with non Notify/SoNode/Base/OutputConnector Fields as targetField.

    • TSubImage<> no longer contains a cursor. Change your code to either make use of a TSubImageCursor<> or ConstTSubImageCursor<>. Alternatively you may use the TSubImageWithCursor<> class which offers the old cursor behavior of TSubImage<>.

    • The integer voxel types Vector16, Vector, and Vector64 have been removed. See new Common Enhancements / Fixes (MeVisLab) for replacement by new types.

    • ml::PagedImage now caches its state for invalid output images as well, since it turned out to be a performance problem when updateImageProperties is called on invalid output images recursively. In some situations, this requires that you call getOutputImageField(outIndex)->touch() in your code to notify the ML that the output image has changed and that it should call calculateOutputImageProperties again. This is especially the case if you want processAllPages(outIndex) to take into account the new output image state. If you do not want to cause update notifications, you can call getOutputImage(outIndex)->setUpdateOfImagePropertiesNeeded(true) instead, but this should rarely be the case.

  • MeVisLab

    • The Vector2f, Vector3f and Vector4f fields have been renamed to Vector2, Vector3 and Vector4, this affects Python/JavaScript scripts that made use of MLABField.type or MLABField.shortClassName(), which now return "VectorX" instead of "VectorXf".

    • MDL variables OS, OSVERSION, ID, CPU and DATE removed. There is still LINUX/UNIX/MACOS/WINDOWS variables to check the OS

Common Enhancements / Fixes (Modules)

  • A new event type has been added to the ObjMgr. The event 'ConnectedToDatabase' is sent on (re)connection of ObjMgrClients to the database and may be used to update dependent networks/scripts to the current database state.

  • SoShader framework

    • Shaders attached via the shaderObject multifield are now aware of OpenGL context switches

    • Shaders may inject code into the main funtion via GLSL snippets (experimental)

    • SoShaderParameterMLImageProps adds a vec3 NameOfParameter_voxelSize uniform to access the voxel size of an ML image sampler

  • SoGVR framework

    • SoGVRMaskSettings and SoGVRMaskVolume now allow to replace the WorldToVoxel matrix of the mask image (similar to SoGVRTransformedVolume).

    • SoGVRTransformedVolume and SoGVRMaskVolume now correctly load images with three and four color dimensions.

  • New Modules

    • New CompareNetworks module allows to compare *.mlab files both textual and visual

    • InventorRayPicker allows to apply a ray pick action to an inventor scene

    • SwapFlipDimensions allows to swap/flip two dimensions

    • New module WEMVascularSystem generates a smooth 2-manifold surface to represent a vascular system. This module complements SoVascularSystem.

    • The library MLVesselGraph is now available so own modules to compute on vessel graphs or to render vascular systems can be written.

    • New modules to create (FieldValueTestCaseEditor and -Generator), run (FieldValueTestCaseIterator) and convert field-value test cases to CSV (FieldValueTestCaseConvertor).

  • File IO & Data Compression:

    • New wrapped itkImageFileWriter and revisions of wrapper for itkImageFileReader. See ITK/VTK.

    • New macro module LoadAny, a multi file extension/format loader with format detection for images, meshes, and other file types. Opens most readable MeVisLab file formats automatically.

    • New very fast LZF data compressor available in MLImageFormat modules and MLDataCompressorFactory for maximum compression speed (also in SDK and public sources).

    • New LZMA data compressor available in MLImageFormat modules and MLDataCompressorFactory for high compression ratios (also in SDK and public sources).

    • Performance of "Optimize Data" option for MLImageFormatSave/Load (de)compressors (and therefore also of file IO) significantly improved and set automatically if useful (i.e. the user selectable toggle disappeared).

    • New difference coding mode added to some data compressor and in MLImageFormatSave to improve compression ratios sometimes significantly.

    • New mode "Preserve Cache File" in MLImageFormatFileCache allows persistent cache files and reusing them (from) elsewhere.

    • Fix: ImageFormatFileCache does not request useless pages from input any more when reading data from cached file.

    • Performance fix in MLDicomTree: Significant optimization of opening times of .mlimage files with huge dicom tags.

    • Further revisions of all MLImageFormat modules (documentation, internal class hierarchy, browse dialogs, better use of variables in paths, showing all file information in all modules, additional buttons etc.)

    • ImageLoad module now also reads MLImageFormat files.

  • Non scalar image support:

    • New integer voxel types for many dimensions and types available. See new ML features.

    • MPR, MPRPath AccumulateImage, Resample3D, OrthoMPR, Reformat, OrthoSwapFlip, and SoOrthoView2D also operate on non scalar image voxels now.

    • New module TypeFromDimension to create a non scalar voxel image from scalar components of a given dimension, simplifying and speeding up some often used operations.

    • Often requested mode for direct decomposition of non scalar voxels to a certain dimension (e.g., vector to color image or vector to time dimension) is now available with TypeToScalars by a newly selectable output dimension.

    • 16 new (and often requested) unary operations on non scalar voxels in Type/TensorArithmetic1 (especially operations with constants, for reordering, and sorting, Phong calculation). Some incorrect sign calculations in Comp Mul and Comp Sum modes fixed. Now these module also support float based processing, i.e. implicit conversions are reduced/removed to speed up operations.

    • View2D and View2DExtensions show all values of non scalar input voxels (enabled by default). This is configurable in View2D Options panels and its settings panel under "Voxel Value". Already saved modules reload former behavior to provide compatibility.

  • Python

    • New module PythonArithmetic is similar to Arithmetic and offers to implement ML image processing by writing the processing code using inline Python/NumPy code in the panel of the module.

  • ImageCalculationDiagnosis offers diagnosis information about the ML image calculation properties of the connected input image to debug and optimize ML modules.

  • CSO:

    • Many improvements for CSOConvertTo3DMask.

    • Fixed multi-threading related bugs for CSOConvertToImage.

    • The module WEMClip now offers the generation of CSOs along the clipped WEM border.

  • ITK/VTK:

    • Upgrade to VTK version 5.7 from 30th of April 2010, about 346 new modules added, 33 removed, many more changed. See any vtk module help for details.

    • Bug fix: Missing shader support has been fixed.

    • Upgrade to ITK version 3.19 from April, 29th, 2010, 10-20pm MET from the CVS repository from http://www.itk.org. See any itk module help for details.

      • Fix in conversion between ML and ITK patient coordinate system which occurred when coordinate systems were rotated.

      • Revised: itkImageFileReader supports non scalar voxel types, uses less memory, has new open and close buttons, provides better path proposals while browsing and the options to enable/disable sub voxel shift in patient coordinate system.

      • New: itkImageFileWriter wrapped, providing the option to save images in numerous file formats and scalar and non scalar voxels types.

      • Many modules now are compiled also for 6 dimensions to support non 2D/3D cases.

      • Some improved example networks (of some itkLevelSet-, itkFastMarching-, and itkVectorConnectedComponentImage filters).

      • Invalid usage of flat kernel elements removed.

      • Some modules compiled with incorrect input/output type combinations fixed.

      • Metric modules revised: New setting makes it configurable when to update the FixedImageRegions parameter.

      • ITKSupport is part of the public sources now.

  • Misc

    • New module DicomTagBrowser which offers an improved view over DicomTagViewer of an image's DICOM tags

    • BaseBypass changed its behavior: It disconnects input and output if bypassing is off

    • MinMaxScan and BoundingBox update behavior changed: Since both modules cannot buffer the input image, (auto)UpdateMode == "off" was removed and redirected to "clear".

    • MergeRegions:

      • Fixed output image region computation for cases where the output world boundaries exactly hit the voxel boundaries (previously the box was one voxel to large in these cases). Now consistent with SubImage behavior, except that the MergeRegions module still allows for empty boxes.

      • Improved notification behavior

      • Many small improvements/fixes.

    • Marked output fields as non-persistent in many modules to improve diff-behavior of .mlab files

    • Decreased amount of unnecessary output notifications for various modules

    • Implemented bypassing for MinMaxScan when datatype does not change

    • Surround: Added border handling to UI (can be important if object boundary touches image border)

    • IntervalThresh Bugfixes:

      • For newMin/newMax: Disabled any clipping with respect to the input image type. This is no problem since no sliders and thus no min/max values are required (previously the value clipping could cause unwanted min/max values for subsequent images)

      • For center/width/min/max: Made sure to internally clamp the thresholds explicitly to the input image datatype range before their application (previously, a cast was performed which could result in false thresholds)

      • Now also clipping user values and computed output min/max against datatype boundaries.

    • Fixed Reformat crash: Previously, the Reformat module would crash in VirtualVolume mode under certain conditions: 1. Both previously invalid inputs were validated at the same time (possibly because they were derived from the same updated image). 2. The notification from the right input (input1) arrived first. 3. An ML module with an auto-update functionality requesting image data was located behind the reformat module.

    • Counter can now also handle floating point values

    • Added fieldHelper.js and fieldHelper.py script files for some convenience scripting functionality (mainly connecting fields/setting field values only if the field is not already connected/the field value is not identical, thus improving performance by preventing unwanted notifications)

    • StopWatch now has a 'pause' functionality

    • ExtractLabels now has up to 20 outputs and allows comments for each output

    • ImageLoadMulti:

      • Fixed an error that could occur when pressing 'parse list' from the parser setting UI

      • Added an option to treat all paths as relative, even when starting with a \, / or C: (disabled by default).

  • Fraunhofer MEVIS Release Packages (ThirdParty / Foundation / Release):

    • OpenCL support + MLOpenCLKernel1 module to experiment with OpenCL

    • OpenCV support (highgui Mac OS X 64-bit is experimental)

    • Module TensorToEigensystem have a new eigenvalue sorting option and has been optimized for performance with a new math library.

    • New modules for DICOM import: DirectDicomImport, DirectDicomImportOutput, DirectDicomImportImageOutput, DirectDicomImportRTOutput, and DirectDicomImportSROutput. This newly developed package supports or example spectroscopy, radio therapy, structured reporting, gantry tilt files (some parts are in SDK interfaces).

    • New DiffusionMRI projects with ~30 new modules for diffusion imaging, including DTI preprocessing, visualiztaion, fiber tracking and fiber clustering

    • New experimental CTCompress2 data compressor available in MLImageFormat modules and MLDataCompressorFactory for CT and MR data (also in SDK and in public sources).

    • Some DICOM tool functions of project DICOMAccessories added to SDK interfaces.

  • Removed the module Window2 and replaced it with the module Scale.

  • Replaced ComposeVolumeFromSlices by ImageComposer module

qmake build system

  • The default for TEMPLATE in *.pro files has changed from TEMPLATE = lib to TEMPLATE = app. If you are using profiles that generate shared libraries/dlls your profile now needs to contain a TEMPLATE = lib line (which was already part of the MeVisLab module wizard in 2.0, but maybe you have profiles which miss that line, these need to be adapted).

  • SoTexture2 no longer crashes on Win+VC8. As a side effect it is no longer possible to load SGI Image files (.rgb). Supported are JPEG + GIF. See also SoMLTexture2 for additional image formats.

  • Added event consumption mechanisms for SoView2DExtensions and SoMouseGrabber.

  • SoView2DAnnotation has more display options.

  • Added new module SoViewportRegion to allow rendering into a specified region of the render area and to combine several renderings in one render area.

  • Added MovieCreator module, to allow writing image sequences as movie files.

  • The new SoMovieScripter module allows to rotate OpenInventor scenes automatically. It also offers the linear interpolation of a variety of variables over time.

  • New Arithmetic module for image arithmetic with general mathematical expressions.

  • New Calculator module for general mathematical expressions.

  • New TubularTracking module for tracking tubular structures and vessels.

  • New GaussSmoothing module for fast filtering with a Gaussian filter kernel.

  • New GaussGradient module for calculating the image gradient using a derivative-of-Gaussian approach.

  • New GaussHessian module for calculating the image Hessian using a derivative-of-Gaussian approach.

  • New Vesselness module for calculating a vesselness measure of an image.

  • New ImageWarp module for deforming an image according to a dense vector field.

  • New TensorToEigensystem module for calculating eigenvectors and eigenvalues for a tensor/matrix image.

  • Added DeMosaic module which extracts 4D data sets from fMRI and DTI data e.g. provided by SIEMENS scanners.

  • GVRImageToVolume and GVRVolumeLoad got a parameter "additionalTransformation" to change the world position of GVR volumes.

  • XMarkerLists:

    • New module InterpolateXMarkerList for interpolating new points in an XMarkerList.

    • New module XMarkerShortestPath for finding the shortest path between two points in an XMarkerList.

    • New module SmoothXMarkerList for smoothing the positions in an XMarkerList.

    • New module TravelingSalesman for finding the shortest route visiting all positions in an XMarkerList.

    • New module XMarkerListBounds for finding a bounding box or sphere enclosing all points in an XMarkerList.

    • New module XMarkerSamplePattern for sampling pre-defined point patterns.

    • New module XMarkerListMaxDistance for finding the max distance between points in an XMarkerList.

    • New module MarkerToMask for converting an XMarkerList into an image mask.

    • New module XMarkerListConvert for converting between world and voxel coordinates.

  • Added two new options to SigmaFilter that are disable by default:

    • Use Linear Weighting: If enabled, the kernel voxels in the Sigma Interval are not all weighted equally, but relative to their distance to its center.

    • Local StdDev Max: Specifies whether and against which value the computed local standard deviation is to be clamped prior to the definition of the sigma interval. This can be useful if there is a known maximum of the noise level, but adaptive filtering is still desired in the areas with lower noise.

  • RegionGrowing:

    • Fixed a missing enum string bug that could cause a crash on some platforms. Now all 4D neighborhoods are associated with the correct enum item name.

    • Previously, the DICOM tags RescaleIntercept and RescaleSlope were only read correctly if 'auto update unit type' was enabled. Now this happens always if 'HU' is selected as unit type (no matter if automatically or manually).

    • Previously, the unit type was not auto-updated when 'auto update unit type' was enabled with an already connected input image. This is now fixed.

    • Now the default HU intercept for images with no such DICOM information is 0 instead of -1024.

    • Reduced the number of (unnecessary) output notifications.

    • Output values are no longer clamped to the uint16 range.

    • Fixed some memory leaks introduced by the 4D extension.

    • Fixed boundary overlap computation for 4d images.

    • Improved 64 bit support.

  • MergeRegions:

    • MergeRegions now supports up to 20 in- and outputs (max number can be changed in MergeRegions.h).

    • Explicit region selection adapted, requires re-save of network to remove warnings. Deprecated modes still supported though, should be fully backwards compatible.

    • Inactive in/outputs are hidden in the MeVisLab module representation. Default number of in/outputs now 2.

    • Added some new merge modes.

    • Reduced the amount of inconsistencies in the merge modes, more consistent and better documented fillValue handling.

  • New MacroModule CombineLabels: The CombineLabels module is designed to simplify label image handling by allowing to add objects to an existing label image or combine them to create a new one. In contrast to mere OR operations with specified bitmasks, the module supports the invertible encoding of all pow(2, n) objects that can be represented by an n-bit label image and thus their separate extraction using the ExtractLabels module.

  • New Module ExtractLabels: The ExtractLabels module is designed to simplify label image handling by allowing to extract up to 10 objects identified via a specific (sub)bitmask from a given (integer) label image. In contrast to a mere AND operation with the bitmask, it allows the separate extraction of any of pow(2,n) objects that can be represented by an n-bit label image.

  • CSO:

    • CSOFilter: Implemented the filtering much more efficient.

    • CSOConvertTo3DMask: The starting condition for scanning the surface is more stable now. Also added a debug mode for very large surfaces / huge amount of CSOs.

    • CSOConvertToImage: Fixed an issue with the calculation of the voxel bounding box.

    • CSOBase: Fixed some issues with the computation of the normal and area of a CSO.

    • SoView2DCSOEditor:

      • The display of and the interaction with a CSO can now be limited to CSOs that lie in the current viewer's plane.

      • If a CSO is edited so that it would be not in-plane anymore, it can optionally be auto-leveled.

    • SoCSO3DVis supports now a StylePalette.

  • WEM:

    • New module WEMPVL that generates PVLs for existing WEMs and can be used for testing.

    • Fixed issues with the copying of WEMPVLs; PVL values are also now generated for newly added primitves (i.e. in WEMSubdivide).

    • New module WEMMerge that merges all patches of incoming WEMs into one output WEM.

    • Added methods to automatically close holes in a WEM.

    • New modules SoView2DWEMContour, SoWEMInteract and WEMExtrude: can be used to draw contours on a 3D viewer and to extrude those contours to become a WEM which in turn can be used with the WEMBoolOp to interactively shape surfaces.

  • ITK:

    • Upgrade to ITK version 3.9 from September, 4th, 2008. Some modules wrapping classes from itk review directory have been removed since licensing is not clear or since they were not useful. For details see technical notes in module help of any wrapped itk module.

  • VTK:

    • Upgrade to VTK version 5.3 from September, 3rd, 2008. For details see technical notes in module help of any wrapped vtk module.

Mac OS X Edition

  • New Features:

    • MeVisLab IDE:

      • This release has been optimized to run on Mac OS X 10.5 (Leopard) or better. As a result, MeVisLab does no longer run on Mac OS X 10.4 (Tiger).

      • The MeVisLab application bundle now contains a debug and a release mode version of MeVisLab that can be started separately (press the Option key during launch to toggle the version; other methods to choose a version include the Preferences dialog or command line options).

      • An option has been added to the Preferences that allows you to choose an alternative IDE toolkit style (used for cross-platform application development).

      • MeVisLab is now Time Machine aware, log and temporary files are excluded from backup.

      • The Busy Cursor has been replaced by a more descriptive panel using an indeterminated progress indicator + text.

      • Additional document icons for ML Image (.mlimage), GVR (.gvr), and Open Inventor (.iv) files have been included.

    • Image Formats:

      • A new ML Image IO (a.k.a. MFL) plugin has been included that interfaces with the Mac OS X Image IO framework and makes most of the Mac OS X image formats readable by MeVisLab (e.g. ImageLoad). Some of the new formats now supported are: JPEG-2000, Adobe Photoshop, Camera-RAW (Canon, Nikon, ...), GIF, Radiance, Quicktime Images, DNG, PICT, Targa, SGI Image, Windows + Mac Icons, PDF Images. Images may contain multiple layers.

    • DicomService:

      • The DicomService is now part of the MeVisLab application bundle and does no longer require a separate download.

    • SDK:

      • The MeVisLabProjectGenerator (a.k.a. MacProfileTranslator) has been completely rewritten and may now be used in GUI mode (default) or from the command line (see '.../MeVisLab.app/Contents/Support/MeVisLabProjectGenerator.app/Contents/MacOS/MeVisLabProjectGenerator --help' for available options).

      • Support for the RELATEDFILES project variable (.pro files) has been added. It allows you to add related files (e.g. .def or .html files) to a 'Related Files' group in the 'Groups & Files' list of your Xcode workspace window for quick access.

    • Documentation:

      • Expanded and revised users guide MeVisLab Mac OS X Edition.

      • New document OsiriX MeVisLab Bridge.

    • Modules:

      • New ML module VideoCapture, that uses Core Video to provide live video input for all video devices supported by Mac OS X - try your iSight (also in SDK interfaces).

      • Updated OsiriX MeVisLab Bridge that supports and requires OsiriX 3.3 or later.

  • Bug Fixes:

    • MeVisLab IDE:

      • The hidden panel issue has been fixed (module panels did not show up sometimes).

      • The styles font size mismatch between Mac OS X and Windows version has been resolved (now the same font size given in point results in approximately the same pixel size on Mac OS X and Windows).

      • The automatic calculation of available texture memory for newer graphics cards has been improved.

  • Important:

    • Some of the MeVisLab helper tools have changed their name and/or id. Sometimes the Mac OS X application database (a.k.a. launch services database) does not detect the changes as soon as you would like. To be on the safe side, execute the following command-line in the Terminal to rebuild the application database after you've installed MeVisLab:

    • /System/Library/Frameworks/CoreServices.framework/Frameworks/LaunchServices.framework/Support/lsregister             -kill -r -domain local -domain system -domain             user
  • Notes:

    • Leave the available texture memory setting in the MeVisLab preferences untouched for the new MacBook Pro with NVIDIA 9400&9600 chipset (5th generation), MeVisLab will automatically calculate the exact amount of texture memory for the currently active graphic chip (according to the energy settings). You may remove any manual overwriting of the texture memory setting by executing the following command-line in the Terminal:

    • defaults delete de.mevis.MeVisLab             GlobalSettings.TextureMemoryInMB

Windows Edition

  • Known issues:

    • 64bit version of MeVisLab is missing the ctypes Python module, because this cannot be build on 64bit Windows.

Linux Edition

  • Changes of the development scripts:

    • MeVisLab.sh and init.sh do not exist anymore.

    • New scripts exist in >MeVisLab-Install-Path</bin. Their purpose is to call commands with certain environment variables set:

      • MeVisLab and MeVisLab_d will start MeVisLab in release and debug mode.

      • mlmake will build MeVisLab projects. It will create the makefiles if they do not exist already by calling the bash script next to the pro-file.

      • mlgdb starts the gdb. If no arguments are given, then MeVisLab will be debugged.

      • MeVisLabPackageScanner runs the MeVisLab package scanner.

      • ToolRunner starts the tool runner.

      • mlbash starts a bash session.

      • mlcodeblocks starts the codeblocks IDE.

  • Improved Scripting consoles

    • Advanced JavaScript and Python completion.

    • Context sensitive help (F1, ⌘+?).

  • Enhanced Scripting methods:

    • MLAB.showInformation()

    • Fixed auto-reloading of modules when a python file was changed after it had a syntax error.

    • Python errors are now printed with the courier font so allow locating the ^ marker in syntax errors.

    • If a MDL command is connected to a Python function/method, the Python function may now have less arguments than the command provides. Surplus arguments are ignored.

  • MDL

    • TextView now supports showLineNumbers = BOOL and syntaxHighlighing = (Python|QSA|MDL|GLSL).

    • LineEdit: new command lostFocusCommand.

    • Now the Toolbox Reference uses improved doxygen layout, many classes and files have better, fixed or completed documentation and alphabetical class index.

Core Revision

  • Glut removal: Glut was only provided as a prebuild binary for the windows platform. Options would have been to provide a 64bit version of glut or to remove it from netsrc. The second choice has been selected (Glut was used for font rendering only, but libraries like ftgl can handle that much better.).

    • Removed glut from netsrc.

    • Added a bridge to MLOpenGL (see mlGL2DFont.{h,cpp}).

    • Examples of usage can be found in MLMiscModulesInv (see mlDiagram2D.{h,cpp}) and SoView2D (extends the GL2DFont class toward text rendering and usage of unicode strings).

  • GL and GLU removal: Both libs should be available on any recent system (as far as it is known, exceptions have been Win95, Win98 and WinME).

  • MLSystemInfo: Inlined assembly is not supported by the VC8-64 compiler. Therefore gathering system information has to be done with outlined assembly on this platform. This is done inside this new project that returns information on available extensions (like MMX, SSE, 3DNow, ...), number of virtual processors, cache sizes and other CPU info.

Common Enhancements / Fixes (Modules)

  • WEM library reworked: a WEM is now actually a list of WEMPatches of different type (WEMTrianglePatch, WEMQuadPatch or WEMPolygonPatch).

    • Split the WEM library into a core part and into a modules part (MLWEM and MLWEMModules).

    • Removed: WEMBrowser, WEMClip, WEMMerge

    • Added Mac OS X Quick Look generator (MeVisLabDocuments.qlgenerator) for MeVisLab network files (.mlab) that enables previewing of MeVisLab networks. It requires networks to be saved by MeVisLab running on Mac OS X 10.5 (the preview gets added to the resource fork of the MeVisLab network file, thus does not affect loading and parsing of the network).

    • Added Mac OS X Quick Look support for MeVisLab script (.script) and definition files (.def) via standard Quick Look generators for text on Mac OS X 10.5.

    • Adapted shortcuts to be more consistent on Mac OS X.

    • Autodetect amount of video RAM on the graphics card (used by the volume renderer and other GPU-intensive tasks).

  • MeVisLab Mac OS X Edition User's Guide changes:

    • PowerPC sections removed

    • Spotlight importer plugin added

    • Quick Look integration added

    • Setup of User Projects Location added

    • Using the Module Wizards added

    • Creating an Xcode project from a .pro file updated

    • Debugging MeVisLab modules with Xcode added

      OS X 10.5 (Leopard). Please choose the appropriate installer for your Mac OS X version.

  • Module changes:

    • Added an experimental bridge between MeVisLab and OsiriX 3.0 (Advanced Mac OS X PACS Viewer) consisting of the OsiriXMeVisLabBridge plugin for OsiriX 3.0 and the MeVisLab module OsiriXBridge. This bridge enables OsiriX to send datasets directly to the MeVisLab imaging pipeline using a standard ImgLoad module (see the example network of the OsiriXBridge module). After processing the dataset, MeVisLab may send the modified data back to OsiriX. The plugin and the module require Mac OS X 10.5 (Leopard). The source codes of both the plugin and the module are included in the MeVisLab public sources package

    • Added check for user interaction in volume renderer (GVR); rendering large volumes should be more responsive now.

  • Scripting changes:

    • Added MLAB.macIsApplicationRunning(bundleId)

  • SDK changes:

    • Added MacOSSupport SDK that wraps Mac OS X specific functionality in C++ classes. See the MeVisLab Toolbox Reference.

    • Added AppleScript xcode-prepare-debug.applescript to automatically setup an MeVisLab module Xcode project for debugging (located within the MeVisLab.app bundle in /Contents/SharedSupport/Scripts/).

Linux Edition

  • All projects are now linked with the option '-z defs' in order to check all symbols at linking time. To turn this option off, add a CONFIG += NO_LIBRARY_DEPENDENCY_ERROR_CHECK to a project's .pro-file.

MeVisLab Public Sources Installer

  • Sources of many projects added:

ML, mlLinearAlgebra, mlUtils and Image Processing For details about the following changes see the ML release notes in mlDoc.h.

  • New version number 1.8.67.23.86 which includes binary and compile interface changes. Some source will require updates before they compile again.

  • Fixed: day() function in DateTime class now returns the correct day instead of always 0.

  • Many constants and macros (e.g. from mlLinearAlgebraDefs.h), ML and mlUtils without ML_-prefix renamed or even removed if they are available on common system.

  • Many interfaces, parameters and internal structures changed for 64 port, activation of 64 bit warnings on VC8 and non WIN32 platforms.

  • New and changed image processing properties in BaseOp class for bypassing, multithreading.

  • Revision of basic multithreading support in mlUtils, new class Mutex introduced which replaced mlCriticalSection.

  • File system interface in mlUtils changed for 64 bit fixes and new functions added.

  • Partial refactoring and revision of header files of project MLBase. Some stuff now located in its own header files such as CurveData, CurveList (from mlDiagramData.h), ParserBase, BaseItemParser (from mlListParser.h).

  • Access to id of BaseItem only via functions from now on.

  • New macros ML_PRINT_INFO and ML_PRINT_INFORMATION.

  • Bugfixes in cursor movements and new functions for bounding box calculations and BitImage to BitImage copying in BitImage class.

  • Fixed: Calculation of image statistics in ImageStat module when image has more than 3 dimensions.

  • Runtime type system in mlUtils has new functions or paarmeters for class, dll, and inheritance dependencies.

  • Fixed: MLImageFormatLoad cannot read nonwritable files.

  • Many sections in ML Guide improved with new details and examples.

  • Fixed: TextureFilter module crashing on non Win32 platforms.

  • Fixed: KernelEditor creating wrong kernel strings on non Win32 platforms.

  • Fixed: TimeCounter in mlUtils used/returned incorrect time units on different platforms. This lead to complete revision of the class interface. Interface was not clear enough such that a complete revision was necessary. It is not compile compatible any more and requires revision of the places of use. See header or SDK documentation for new interfaces.

  • New module FloydSteinberg.

  • New module ImageCompare.

  • New Module CommandNotifyer.

  • New module BitImageArithmetic, MLToBitImage, and BitImageToML in project BitImageTools as well as improved source box/region suppport and bug fixes.

ITK & VTK:
