• Added documentation concerning the new package structure and all new tools.
• Added support for Postgres and SQLite databases (see the MLABSqlDatabase and MLABSqlQuery scripting classes for general database support).
• Other changes to the IDE:
• The Python scripting console can be set to execute default commands on startup. These can be edited in the preferences dialog. Default is "from mevis import *".
• MeVisLab got a new commandline option "-quick" for faster startup performance when the module database has not changed. Under Windows, look out for the MeVisLab icons with the red arrows on it to start MeVisLab quickly.

• Renamed a number of modules. The old name is left as the 'deprecatedName' to ensure compatibility with old networks. Renamed modules are: CalcGradient, CalcVolume, CatCurves, ConcatImages, ConnectComp, ConstImg, ExtConvolution, ImgLoad, ImgPropConvert, ImgSave, ImgStat, JointHist, JointHistMask, MarkerStat, StdDeviation, Subimage, SubImageStat, VoxValueRescale, SoFrameBufferSampler, SoGVRVolRen, SimpleImgStat. The new names are mostly the non-abbreviated version, e.g. ImgStat becomes ImageStatistics.
• Added SoShadow* modules group to cast and interact with shadows.
• ML image file format default file extension has changed from .mif to .mlimage (.mif will still be recognized though).
• 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.

• 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.

• 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.
• 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 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 in the Terminal:
• defaults delete de.mevis.MeVisLab GlobalSettings.TextureMemoryInMB.

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

Version 1.6.1 (2008-08-24)

• ML:
• Subtle bug in priority management of the ML Cache fixed. It required an ML interface change and update to version number 1.8.68.23.87 in mlVersion.h. Relink all libraries dependent on the ML.

• 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.
• SDK
• Module wizard for ML modules improved with many new features and tooltips with references into detail documentation of ML Guide.
• Now the Toolbox Reference uses improved doxygen layout, many classes and files have better, fixed or completed documentation and alphabetical class index.

• 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.

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

• Removed: WEMBrowser, WEMClip, WEMMerge
• Renamed: WEMCollapseEdges -> WEMReducePolygons
• Renamed: WEMSplitEdges -> WEMSubdivide
• Renamed: WEMPurge -> WEMDemergePatches

• Split the CSO library into a core part and into a modules part (MLCSO and MLCSOModules).
• Reworked CSOConvertToImage: this module works now with a page-based concept and has a OnDemand mode.
• New processors: CSOModifyProcessor and CSOBulgeProcessor, both to modify existing CSOs.
• New processor: CSOLiveWireProcessor for a semi-automatic segmentation.
• SoView2DCSOEditor displays closed and fully visible CSOs in a filled manner.
• CSOIsoGenerator offers several filtering and smoothing options.
• SoGVRVolRen no longer supports legacy hardware LUTs (using EXT_paletted_texture) , which was last seen on NVidia GeForce3 cards (but rendering still works on these cards).
• SoGVRSecondaryLUT and SoGVRSecondaryVolume support a variable number of LUTs and additional octree volumes in the renderer.

• MarkerListInspector: Lots of new options.

There are also a lot of other minor changes which don't appear in this document.

• MeVisLab changes:
• MeVisLab does no longer run on PowerPC-based Macintosh computers. This release has been optimized to run on Macintosh computers with an Intel processor.
• Added Mac OS X 10.5 (Leopard) compatibility; MeVisLab 1.6 runs on Mac OS X 10.4.11 or 10.5.x
• Added 'Restart With Current Networks' feature (File menu).
• Improved handling of non-latin1 language settings.
• Added multiple instances support, now more than one MeVisLab application can be used at the same time.
• Added command-line support ('cmdline' license feature required).
• Added Mac OS X Spotlight metadata importer (MeVisLabDocuments.mdimporter) that allows indexing of uncrypted MeVisLab script (.script) and definition files (.def).
• 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
  • Developing on Leopard for Tiger added
  • Obtaining Source Codes of MeVisLab Modules added
  • Integrating MeVisLab with OsiriX added
• MeVisLabDicomService changes:
• Added Mac OS X 10.5 compatibility. There are separate installers for Mac OS X 10.4 (Tiger) and Mac
  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/).

• 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.

Sources of many projects added:
• MLBase

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.
