Detailed Description

template<typename TPixel>
class mitk::ItkImageToImageFilterAdapter< TPixel >

adapter class, that encapsulates any itk::ImageToImageFilter

This filter converts a mitk::Image to an itk::Image, executes the itkFilter and converts the itk::Image back to a mitk::Image as output. Either call SetSingleFilter() to encapsulate one itk::ImageToImageFilter, or SetFirstFilter() and SetLastFilter() to encapsulate a whole itk pipeline.

template<typename TPixel >

void mitk::ItkImageToImageFilterAdapter< TPixel >::GenerateData

(

)

[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.

Reimplemented from mitk::ImageSource.
