◆ AllocateUpdateBuffer()

template<typename TInputImage, typename TOutputImage, typename TParentImageFilter = FiniteDifferenceImageFilter<TInputImage, TOutputImage>>
void itk::GPUFiniteDifferenceImageFilter< TInputImage, TOutputImage, TParentImageFilter >::AllocateUpdateBuffer ( )
overrideprotectedpure virtual

This method allocates a temporary update container in the subclass.

Implemented in itk::GPUDenseFiniteDifferenceImageFilter< TInputImage, TOutputImage, TParentImageFilter >, and itk::GPUDenseFiniteDifferenceImageFilter< TDisplacementField, TDisplacementField, TParentImageFilter >.

overrideprotectedpure virtual

This method can be defined in subclasses as needed to copy the input to the output. See DenseFiniteDifferenceImageFilter for an implementation.

Implemented in itk::GPUPDEDeformableRegistrationFilter< TFixedImage, TMovingImage, TDisplacementField, TParentImageFilter >, itk::GPUDenseFiniteDifferenceImageFilter< TInputImage, TOutputImage, TParentImageFilter >, and itk::GPUDenseFiniteDifferenceImageFilter< TDisplacementField, TDisplacementField, TParentImageFilter >.

◆ GenerateInputRequestedRegion()

void itk::GPUFiniteDifferenceImageFilter< TInputImage, TOutputImage, TParentImageFilter >::GenerateInputRequestedRegion ( )
overrideprotected

FiniteDifferenceImageFilter needs a larger input requested region than the output requested region. As such, we need to provide an implementation for GenerateInputRequestedRegion() in order to inform the pipeline execution model.

The filter will ask for a padded region to perform its neighborhood calculations. If no such region is available, the boundaries will be handled as described in the FiniteDifferenceFunction defined by the subclass.

◆ ThreadedHalt()

bool itk::GPUFiniteDifferenceImageFilter< TInputImage, TOutputImage, TParentImageFilter >::ThreadedHalt ( void *  )
inlineoverrideprotected

This method is similar to Halt(), and its default implementation in this class is simply to call Halt(). However, this method takes as a parameter a void pointer to the MultiThreaderBase::WorkUnitInfo structure. If you override this method instead of overriding Halt, you will be able to get the current thread ID and handle the Halt method accordingly. This is useful if you are doing a lot of processing in Halt that you don't want parallelized. Notice that ThreadedHalt is only called by the multithreaded filters, so you still should implement Halt, just in case a non-threaded filter is used.
