itk::PeriodicBoundaryCondition< TInputImage, TOutputImage > Class Template Reference

#include <itkPeriodicBoundaryCondition.h>

Detailed Description

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

A function object that determines values outside of image boundaries according to periodic (wrap-around) conditions.

The input to this function object is a neighborhood iterator. This boundary condition object is designed to be given as a template argument to a NeighborhoodIterator or any of the NeighborhoodIterator subclasses.

Constructor & Destructor Documentation

PeriodicBoundaryCondition()

template<typename TInputImage , typename TOutputImage = TInputImage>

itk::PeriodicBoundaryCondition< TInputImage, TOutputImage >::PeriodicBoundaryCondition ( )

default

Default constructor.

Member Function Documentation

GetInputRequestedRegion()

template<typename TInputImage , typename TOutputImage = TInputImage>

RegionType itk::PeriodicBoundaryCondition< TInputImage, TOutputImage >::GetInputRequestedRegion ( const RegionType &  inputLargestPossibleRegion, const RegionType &  outputRequestedRegion  ) const

overridevirtual

Determines the necessary input region for the output region. For this boundary condition, the output region is mapped into the input image index space. If the mapped region crosses an image boundary in some dimension, then the entire size of the image in that dimension is requested. For this reason, it is most memory efficient to request regions that map to regions that do cross image boundaries.

Parameters

inputLargestPossibleRegion	Largest possible region of the input image.
outputRequestedRegion	The output requested region.

Returns

The necessary input region required to determine the pixel values in the outputRequestedRegion.

Reimplemented from itk::ImageBoundaryCondition< TInputImage, TInputImage >.

GetPixel()

template<typename TInputImage , typename TOutputImage = TInputImage>

OutputPixelType itk::PeriodicBoundaryCondition< TInputImage, TOutputImage >::GetPixel ( const IndexType &  index, const TInputImage *  image  ) const

overridevirtual

Returns a value for a given pixel at an index. If the index is inside the bounds of the input image, then the pixel value is obtained from the input image. Otherwise, the pixel at the desired index (modulo the size of the image) is returned.

Parameters

index	The index of the desired pixel.
image	The image from which pixel values should be determined.

Implements itk::ImageBoundaryCondition< TInputImage, TInputImage >.

operator()() [1/2]

template<typename TInputImage , typename TOutputImage = TInputImage>

OutputPixelType itk::PeriodicBoundaryCondition< TInputImage, TOutputImage >::operator() ( const OffsetType &  point_index, const OffsetType &  boundary_offset, const NeighborhoodType *  data  ) const

overridevirtual

Computes and returns a neighborhood of appropriate values from neighborhood iterator data..

Implements itk::ImageBoundaryCondition< TInputImage, TInputImage >.

OutputPixelType itk::PeriodicBoundaryCondition< TInputImage, TOutputImage >::operator() ( const OffsetType &  point_index, const OffsetType &  boundary_offset, const NeighborhoodType *  data, const NeighborhoodAccessorFunctorType &  neighborhoodAccessorFunctor  ) const

overridevirtual

Computes and returns the appropriate pixel value from neighborhood iterator data, using the functor.
