Constructor & Destructor Documentation

ml::ZeroCrossingsFilter::ZeroCrossingsFilter

(

)

Constructor.

Initializes the fields, the members and the field connections with the image output.

Note that with the following method calls an additional field interface is created as described in KernelModule and KernelBaseModule:

• _createKernelExtentFields();
• _createImageIntervalFields (0, 1024, true, false);
• _createKernelIntervalFields (0, 1024, true, false);
• _createMakeSphericalField();
• _createExternalKernelFields (true, false);
• _createKernelInfoField();

Also available are the fields access methods from KernelBaseModule:

• getBorderHandlingFld()
• getFillValueFld()

Member Function Documentation

ml::ZeroCrossingsFilter::CALC_ROW_H

(

)

[protected]

The implementation of the calculateOutputSubImage() method overloaded from Module is done in this macro.

It implements page border handling and a dispatcher to call the correct template version of calcRow() with the correct parameters. Note that CALC_ROW_CPP() also needs to be added in the .cpp file.

template<typename DATATYPE >

void ml::ZeroCrossingsFilter::calcRow	(	MLsoffset *	indexTab,
		size_t	indexTabSize,
		MLsoffset	srcVoxelOffset,
		size_t	numVox,
		DATATYPE *	inCursor,
		DATATYPE *	outCursor,
		const ImageVector &
	)		[protected]

In this virtual template method the filtering of one row needs to be implemented.

It will be called by the CALC_ROW_H() / CALC_ROW_CPP() macro.

virtual void ml::ZeroCrossingsFilter::calculateOutputImageProperties

(

int

outIndex

)

[protected, virtual]

Computes the output image properties for output outIndex.

Reimplemented from ml::KernelModule.

ml::ZeroCrossingsFilter::ML_MODULE_CLASS_HEADER

(

ZeroCrossingsFilter

)

[protected]

Macro to declare methods/functions of the runtime system interface of this class.

It is defined in mlRuntimeSubClass.h. Note that this class must be registered in the project initialization file by calling the initClass() function implemented in this macro.
