Member Function Documentation

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

Standard pipeline method. While this class does not implement a ThreadedGenerateData(), its GenerateData() delegates all calculations to an NeighborhoodOperatorImageFilter. Since the NeighborhoodOperatorImageFilter is multithreaded, this filter is multithreaded by default. Reimplemented from itk::ImageSource< TOutputImage >.

template<class TInputImage, class TOutputImage> virtual void itk::DerivativeImageFilter< TInputImage, TOutputImage >::GenerateInputRequestedRegion (    )  throw (InvalidRequestedRegionError) [virtual]

DerivativeImageFilter needs a larger input requested region than the output requested region (larger in the direction of the derivative). As such, DerivativeImageFilter needs to provide an implementation for GenerateInputRequestedRegion() in order to inform the pipeline execution model. See also: ImageToImageFilter::GenerateInputRequestedRegion() Reimplemented from itk::ImageToImageFilter< TInputImage, TOutputImage >.

template<class TInputImage, class TOutputImage> virtual const char* itk::DerivativeImageFilter< TInputImage, TOutputImage >::GetClassName (    )  const [virtual]

Run-time type information (and related methods). Reimplemented from itk::ImageToImageFilter< TInputImage, TOutputImage >.

template<class TInputImage, class TOutputImage> virtual unsigned int itk::DerivativeImageFilter< TInputImage, TOutputImage >::GetDirection (    )  [virtual]

Standard get/set macros for filter parameters.

template<class TInputImage, class TOutputImage> virtual unsigned int itk::DerivativeImageFilter< TInputImage, TOutputImage >::GetOrder (    )  [virtual]

Standard get/set macros for filter parameters.

template<class TInputImage, class TOutputImage> itk::DerivativeImageFilter< TInputImage, TOutputImage >::itkStaticConstMacro (  ImageDimension   , unsigned    int, TOutputImage::ImageDimension    )

Extract some information from the image types. Dimensionality of the two images is assumed to be the same.

template<class TInputImage, class TOutputImage> Pointer itk::DerivativeImageFilter< TInputImage, TOutputImage >::New (    )  [static]

Method for creation through the object factory. Reimplemented from itk::Object.

template<class TInputImage, class TOutputImage> void itk::DerivativeImageFilter< TInputImage, TOutputImage >::PrintSelf (  std::ostream &    os, Indent    indent )  const [protected, virtual]

Methods invoked by Print() to print information about the object including superclasses. Typically not called by the user (use Print() instead) but used in the hierarchical print process to combine the output of several classes. Reimplemented from itk::ImageToImageFilter< TInputImage, TOutputImage >.

template<class TInputImage, class TOutputImage> virtual void itk::DerivativeImageFilter< TInputImage, TOutputImage >::SetDirection (  unsigned int    _arg )  [virtual]

Standard get/set macros for filter parameters.

template<class TInputImage, class TOutputImage> virtual void itk::DerivativeImageFilter< TInputImage, TOutputImage >::SetOrder (  unsigned int    _arg )  [virtual]

Standard get/set macros for filter parameters.
