Detailed Description

template<typename TInputImage, typename TOutputImage = TInputImage>
class itk::RecursiveSeparableImageFilter< TInputImage, TOutputImage >

Base class for recursive convolution with a kernel.

RecursiveSeparableImageFilter is the base class for recursive filters that are applied in each dimension separatedly.

This class implements the recursive filtering method proposed by R.Deriche in IEEE-PAMI Vol.12, No.1, January 1990, pp 78-87.

Member Function Documentation

template<typename TInputImage, typename TOutputImage = TInputImage>
void itk::RecursiveSeparableImageFilter< TInputImage, TOutputImage >::ApplyRecursiveFilter unsigned int    dimension [protected]
 

Apply the recursive filter along one of the dimensions of the image. This allow to filter each one of the dimensions of an image separately. Sigma is given in length units so the spacing between pixels is taken into account. This is relevant for anisotropic images.

template<typename TInputImage, typename TOutputImage = TInputImage>
virtual void itk::RecursiveSeparableImageFilter< TInputImage, TOutputImage >::ComputeFilterCoefficients bool    symmetric [protected, pure virtual]
 

Compute Recursive Filter Coefficients this method prepares the values of the coefficients used for filtering the image. The symmetric flag is used to enforce that the filter will be symmetric or antisymmetric. For example, the Gaussian kernel is symmetric, while its first derivative is antisymmetric.

Implemented in itk::RecursiveGaussianImageFilter< TInputImage, TOutputImage >.

template<typename TInputImage, typename TOutputImage = TInputImage>
void itk::RecursiveSeparableImageFilter< 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::RecursiveSeparableImageFilter< TInputImage, TOutputImage >::FilterDataArray RealType   outs,
const RealType   data,
unsigned int    ln
[protected]
 

Apply the Recursive Filter in an array of data. this method is called for each line of the volume from ApplyRecursiveFilter.

See also:
ApplyRecursiveFilter.

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

GenerateData (apply) the filter.

Reimplemented from itk::ImageSource< TOutputImage >.

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

RecursiveSeparableImageFilter needs all of the input to produce an output. Therefore, RecursiveSeparableImageFilter 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 const char* itk::RecursiveSeparableImageFilter< TInputImage, TOutputImage >::GetClassName   const [virtual]

Reimplemented in itk::RecursiveGaussianImageFilter< TInputImage, TOutputImage >.

template<typename TInputImage, typename TOutputImage = TInputImage>
virtual unsigned int itk::RecursiveSeparableImageFilter< TInputImage, TOutputImage >::GetDirection   [virtual]

template<typename TInputImage, typename TOutputImage = TInputImage>
const TInputImage* itk::RecursiveSeparableImageFilter< TInputImage, TOutputImage >::GetInputImage void

template<typename TInputImage, typename TOutputImage = TInputImage>
void itk::RecursiveSeparableImageFilter< 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 >.

Reimplemented in itk::RecursiveGaussianImageFilter< TInputImage, TOutputImage >.

template<typename TInputImage, typename TOutputImage = TInputImage>
virtual void itk::RecursiveSeparableImageFilter< TInputImage, TOutputImage >::SetDirection unsigned int    _arg [virtual]
 

Set the direction in which the filter is to be applied.

template<typename TInputImage, typename TOutputImage = TInputImage>
void itk::RecursiveSeparableImageFilter< TInputImage, TOutputImage >::SetInputImage const TInputImage *   
 

Set Input Image.

template<typename TInputImage, typename TOutputImage = TInputImage>
virtual void itk::RecursiveSeparableImageFilter< TInputImage, TOutputImage >::SetUp void    [protected, pure virtual]
 

Set up the coefficients of the filter to approximate a specific kernel. typically it can be used to approximate a gaussian or one of its derivatives.

Implemented in itk::RecursiveGaussianImageFilter< TInputImage, TOutputImage >.
