Detailed Description

template<typename TInputImage, typename TOutputImage = TInputImage>
class itk::RecursiveSeparableImageFilter< TInputImage, TOutputImage >

Base class for recursive convolution with a kernel.

RecursiveSeparableImageFilter is the base class for recursive filters that are applied in each dimension separately. If multi-component images are specified, the filtering operation works on each component independently.

This class implements the recursive filtering method proposed by R.Deriche in IEEE-PAMI Vol.12, No.1, January 1990, pp 78-87.

Details of the implementation are described in the technical report: R. Deriche, "Recursively Implementing The Gaussian and Its Derivatives", INRIA, 1993, ftp://ftp.inria.fr/INRIA/tech-reports/RR/RR-1893.ps.gz

Further improvements of the algorithm are described in: G. Farneback & C.-F. Westin, "On Implementation of Recursive Gaussian Filters", so far unpublished.

void itk::RecursiveSeparableImageFilter< TInputImage, TOutputImage >::EnlargeOutputRequestedRegion ( DataObject *  output )

protectedvirtual

RecursiveSeparableImageFilter needs all of the input only in the "Direction" dimension. Therefore we enlarge the output's RequestedRegion to this. Then the superclass's GenerateInputRequestedRegion method will copy the output region to the input.

Apply the Recursive Filter to an array of data. This method is called for each line of the volume. Parameter "scratch" is a scratch area used for internal computations that is the same size as the parameters "outs" and "data". The scratch area must be allocated outside of this routine (this avoids memory allocation and deallocation in the inner loop of the overall algorithm.

Get the image splitter to split the image for multi-threading.

The Splitter object divides the image into regions for threading or streaming. The algorithms on how to split an images are separated into class so that they can be easily be reused. When deriving from this class to write a filter consideration to the algorithm used to divide the image should be made. If a change is desired this method should be overridden to return the appropriate object.

void itk::RecursiveSeparableImageFilter< TInputImage, TOutputImage >::ThreadedGenerateData ( const OutputImageRegionType &  outputRegionForThread, ThreadIdType  threadId  )

protectedvirtual

If an imaging filter can be implemented as a multithreaded algorithm, the filter will provide an implementation of ThreadedGenerateData(). This superclass will automatically split the output image into a number of pieces, spawn multiple threads, and call ThreadedGenerateData() in each thread. Prior to spawning threads, the BeforeThreadedGenerateData() method is called. After all the threads have completed, the AfterThreadedGenerateData() method is called. If an image processing filter cannot support threading, that filter should provide an implementation of the GenerateData() method instead of providing an implementation of ThreadedGenerateData(). If a filter provides a GenerateData() method as its implementation, then the filter is responsible for allocating the output data. If a filter provides a ThreadedGenerateData() method as its implementation, then the output memory will allocated automatically by this superclass. The ThreadedGenerateData() method should only produce the output specified by "outputThreadRegion" parameter. ThreadedGenerateData() cannot write to any other portion of the output image (as this is responsibility of a different thread).
