#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
inputLargestPossibleRegionLargest possible region of the input image.
outputRequestedRegionThe output requested region.
Returns
The necessary input region required to determine the pixel values in the outputRequestedRegion.

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

◆ 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
indexThe index of the desired pixel.
imageThe image from which pixel values should be determined.

Implements itk::ImageBoundaryCondition< TInputImage, TOutputImage >.

◆ itkOverrideGetNameOfClassMacro()
