Member Function Documentation

template<class TInputImage, class TOutputImage>
void itk::DerivativeImageFilter< TInputImage, TOutputImage >::GenerateData   [protected, virtual]
 

Standard pipeline method. While this class does not implement a ThreadedGenerateData(), its GenerateData() delegates all calculations to an NeighborhoodOperatorImageFilter. Since the NeighborhoodOperatorImageFilter is multithreaded, this filter is multithreaded by default.

Reimplemented from itk::ImageSource< TOutputImage >.

template<class TInputImage, class TOutputImage>
virtual void itk::DerivativeImageFilter< TInputImage, TOutputImage >::GenerateInputRequestedRegion   throw (InvalidRequestedRegionError) [virtual]
 

DerivativeImageFilter needs a larger input requested region than the output requested region (larger in the direction of the derivative). As such, DerivativeImageFilter needs to provide an implementation for GenerateInputRequestedRegion() in order to inform the pipeline execution model.
