Detailed Description

template<class TInputImage, class TOutputImage>
class itk::Testing::ComparisonImageFilter< TInputImage, TOutputImage >

Implements comparison between two images.

This filter is used by the testing system to compute the difference between a valid image and an image produced by the test. The comparison value is computed by visiting all the pixels in the baseline images and comparing their values with the pixel values in the neighborhood of the homologous pixel in the other image.

void itk::Testing::ComparisonImageFilter< TInputImage, TOutputImage >::AfterThreadedGenerateData

(

void

)

[protected, virtual]

If an imaging filter needs to perform processing after all processing threads have completed, the filter can can provide an implementation for AfterThreadedGenerateData(). The execution flow in the default GenerateData() method will be: 1) Allocate the output buffer 2) Call BeforeThreadedGenerateData() 3) Spawn threads, calling ThreadedGenerateData() in each thread. 4) Call AfterThreadedGenerateData() Note that this flow of control is only available if a filter provides a ThreadedGenerateData() method and NOT a GenerateData() method.

Reimplemented from itk::ImageSource< TOutputImage >.

void itk::Testing::ComparisonImageFilter< TInputImage, TOutputImage >::BeforeThreadedGenerateData

(

void

)

[protected, virtual]

If an imaging filter needs to perform processing after the buffer has been allocated but before threads are spawned, the filter can can provide an implementation for BeforeThreadedGenerateData(). The execution flow in the default GenerateData() method will be: 1) Allocate the output buffer 2) Call BeforeThreadedGenerateData() 3) Spawn threads, calling ThreadedGenerateData() in each thread. 4) Call AfterThreadedGenerateData() Note that this flow of control is only available if a filter provides a ThreadedGenerateData() method and NOT a GenerateData() method.

void itk::Testing::ComparisonImageFilter< TInputImage, TOutputImage >::ThreadedGenerateData	(	const OutputImageRegionType &	threadRegion,
		ThreadIdType	threadId
	)		[protected, virtual]

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