Member Function Documentation

template<typename TInputImage, typename TOutputImage = TInputImage> void itk::GradientMagnitudeRecursiveGaussianImageFilter< TInputImage, TOutputImage >::EnlargeOutputRequestedRegion (  DataObject *  output  )  [protected, virtual]

Give the process object a chance to indictate that it will produce more output than it was requested to produce. For example, many imaging filters must compute the entire output at once or can only produce output in complete slices. Such filters cannot handle smaller requested regions. These filters must provide an implementation of this method, setting the output requested region to the size they will produce. By default, a process object does not modify the size of the output requested region. Reimplemented from itk::ProcessObject.

template<typename TInputImage, typename TOutputImage = TInputImage> void itk::GradientMagnitudeRecursiveGaussianImageFilter< TInputImage, TOutputImage >::GenerateData (  void   )  [protected, virtual]

Generate Data Reimplemented from itk::ImageSource< TOutputImage >.

template<typename TInputImage, typename TOutputImage = TInputImage> virtual void itk::GradientMagnitudeRecursiveGaussianImageFilter< TInputImage, TOutputImage >::GenerateInputRequestedRegion (   )  throw (InvalidRequestedRegionError) [virtual]

GradientMagnitudeRecursiveGaussianImageFilter needs all of the input to produce an output. Therefore, GradientMagnitudeRecursiveGaussianImageFilter 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<typename TInputImage, typename TOutputImage = TInputImage> virtual bool itk::GradientMagnitudeRecursiveGaussianImageFilter< TInputImage, TOutputImage >::GetNormalizeAcrossScale (   )  [virtual]

Define which normalization factor will be used for the Gaussian

template<typename TInputImage, typename TOutputImage = TInputImage> itk::GradientMagnitudeRecursiveGaussianImageFilter< TInputImage, TOutputImage >::itkStaticConstMacro (  ImageDimension  , unsigned  int, TInputImage::ImageDimension  )

Image dimension.

template<typename TInputImage, typename TOutputImage = TInputImage> Pointer itk::GradientMagnitudeRecursiveGaussianImageFilter< TInputImage, TOutputImage >::New (   )  [static]

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

template<typename TInputImage, typename TOutputImage = TInputImage> void itk::GradientMagnitudeRecursiveGaussianImageFilter< 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<typename TInputImage, typename TOutputImage = TInputImage> void itk::GradientMagnitudeRecursiveGaussianImageFilter< TInputImage, TOutputImage >::SetNormalizeAcrossScale (  bool  normalizeInScaleSpace  )

Define which normalization factor will be used for the Gaussian

template<typename TInputImage, typename TOutputImage = TInputImage> void itk::GradientMagnitudeRecursiveGaussianImageFilter< TInputImage, TOutputImage >::SetSigma (  RealType  sigma  )

Set Sigma value. Sigma is measured in the units of image spacing.
