Detailed Description

template<typename TInputImage, typename TOutputImage>
class itk::ShrinkImageFilter< TInputImage, TOutputImage >

Reduce the size of an image by an integer factor in each dimension.

ShrinkImageFilter reduces the size of an image by an integer factor in each dimension. The algorithm implemented is a simple subsample. The output image size in each dimension is given by:

outputSize[j] = max( std::floor(inputSize[j]/shrinkFactor[j]), 1 );

NOTE: The physical centers of the input and output will be the same. Because of this, the Origin of the output may not be the same as the Origin of the input. Since this filter produces an image which is a different resolution, origin and with different pixel spacing than its input image, it needs to override several of the methods defined in ProcessObject in order to properly manage the pipeline execution model. In particular, this filter overrides ProcessObject::GenerateInputRequestedRegion() and ProcessObject::GenerateOutputInformation().

This filter is implemented as a multithreaded filter. It provides a DynamicThreadedGenerateData() method for its implementation.

◆ DynamicThreadedGenerateData()

template<typename TInputImage , typename TOutputImage >

void itk::ShrinkImageFilter< TInputImage, TOutputImage >::DynamicThreadedGenerateData ( const OutputImageRegionType & outputRegionForThread )

overrideprotectedvirtual

ShrinkImageFilter can be implemented as a multithreaded filter. Therefore, this implementation provides a DynamicThreadedGenerateData() routine which is called for each processing thread. The output image data is allocated automatically by the superclass prior to calling DynamicThreadedGenerateData(). DynamicThreadedGenerateData can only write to the portion of the output image specified by the parameter "outputRegionForThread"

◆ GenerateInputRequestedRegion()

template<typename TInputImage , typename TOutputImage >

void itk::ShrinkImageFilter< TInputImage, TOutputImage >::GenerateInputRequestedRegion ( )

overridevirtual

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

overridevirtual

ShrinkImageFilter produces an image which is a different resolution and with a different pixel spacing than its input image. As such, ShrinkImageFilter needs to provide an implementation for GenerateOutputInformation() in order to inform the pipeline execution model. The original documentation of this method is below.
