Detailed Description

template<class TInputImage, class TOutputImage>
class itk::NonThreadedShrinkImageFilter< TInputImage, TOutputImage >

Reduce the size of an image by an integer factor.

NonThreadedShrinkImageFilter reduces the size of an image by an integer factor. The algorithm implemented is a simple subsample. Since this filter produces an image which is a different resolution 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().

Member Function Documentation

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

A version of GenerateData() specific for image processing filters. This implementation will split the processing across multiple threads. The buffer is allocated by this method. Then the BeforeThreadedGenerateData() method is called (if provided). Then, a series of threads are spawned each calling ThreadedGenerateData(). After all the threads have completed processing, the AfterThreadedGenerateData() method is called (if provided). If an image processing filter cannot be threaded, the filter should provide an implementation of GenerateData(). That implementation is responsible for allocating the output buffer. If a filter an be threaded, it should NOT provide a GenerateData() method but should provide a ThreadedGenerateData() instead.

template<class TInputImage, class TOutputImage>
virtual void itk::NonThreadedShrinkImageFilter< TInputImage, TOutputImage >::GenerateInputRequestedRegion  )  [virtual]
 

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

template<class TInputImage, class TOutputImage>
virtual void itk::NonThreadedShrinkImageFilter< TInputImage, TOutputImage >::GenerateOutputInformation  )  [virtual]
 

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