Detailed Description

template<typename DATATYPE, typename KDATATYPE>
class ml::KernelLineApplicatorBase< DATATYPE, KDATATYPE >

The KernelLineApplicatorBase class is designed to implement new kernel based filters to be applied to a line of an mlSubImage and and to write the filtered line to an output mlSubImage.

This class is derived from the LineApplicator which is the minimum class which has to be passed to a applyFiltering function from the KernelTools class to filter a page. The methods applyToLine, getNegativeExtent and getPositiveExtent were be overloaded in class LineApplicator.

The central method is

applyToLine(TSubImageWithCursor<DATATYPE> *inSubImg, TSubImageWithCursor<DATATYPE> *outSubImg, size_t numVox)

which applies the currently set kernel to a line of numVox voxels in the inSubImg and writes the result to outSubImg. Before doing that in both subimages the cursor position must be set adequately. This is usually done by an applyFiltering function from the KernelTools class. So usually there is no need to use this class explicitly if it's not overloaded.

So - if you want to implement a new kernel filter then just overload the virtual method applyToLine and implement your new filter in it.

◆ _defineIndices()

template<typename DATATYPE , typename KDATATYPE >

void ml::KernelLineApplicatorBase< DATATYPE, KDATATYPE >::_defineIndices ( const SubImage & inSubImg )

protectedvirtual

Create the table of offsets from the voxel (0,0,0,0,0,0) of the kernel to any other voxel of the kernel in an inSubImg.

Pass the subimage page to make correct calculations. It's the same like multiplying the coordinates of the kernel elements with inSubImg strides. This method also initializes the member _srcVoxOffset.

◆ _indexTab

protected

Table and variables defined temporarily while filtering a page.

The table contains the offsets from kernel voxel (0,0,0,0,0,0) to all other kernel voxels in the input page. So all input SubImage voxels can be addressed within a page by indexing the base voxel of the kernel in the input subImg. Default is NULL.
