Member Function Documentation

template<typename TInputImage, typename TOutputImage = Image< CovariantVector< typename NumericTraits< typename TInputImage::PixelType>::RealType, ::itk::GetImageDimension<TInputImage>::ImageDimension >, ::itk::GetImageDimension<TInputImage>::ImageDimension >> void itk::GradientRecursiveGaussianImageFilter< 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 = Image< CovariantVector< typename NumericTraits< typename TInputImage::PixelType>::RealType, ::itk::GetImageDimension<TInputImage>::ImageDimension >, ::itk::GetImageDimension<TInputImage>::ImageDimension >> void itk::GradientRecursiveGaussianImageFilter< TInputImage, TOutputImage >::GenerateData (  void   )  [protected, virtual]

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

GradientRecursiveGaussianImageFilter needs all of the input to produce an output. Therefore, GradientRecursiveGaussianImageFilter 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 >.

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

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 >.

Define which normalization factor will be used for the Gaussian

template<typename TInputImage, typename TOutputImage = Image< CovariantVector< typename NumericTraits< typename TInputImage::PixelType>::RealType, ::itk::GetImageDimension<TInputImage>::ImageDimension >, ::itk::GetImageDimension<TInputImage>::ImageDimension >> void itk::GradientRecursiveGaussianImageFilter< TInputImage, TOutputImage >::SetSigma (  RealType  sigma  )
