#include <itkImageBoundaryCondition.h>

Detailed Description

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

A virtual base object that defines an interface to a class of boundary condition objects for use by neighborhood iterators.

A boundary condition object supplies a phantom pixel value when given a neighborhood of (pointers to) image values, the (ND) index of the phantom pixel, and its (ND) offset from the boundary. The index of the phantom pixel is relative to the "upper left-hand corner" of the neighborhood (as opposed to its center).

Associated Types Description

PixelType The data type of the return value. PixelPointerType A pointer to PixelType. PixelPointerTypeNeighborhood A neighborhood of PixelPointerTypes that points to the pixel values in an image neighborhood.

Determines the necessary input region for an output region given the largest possible region of the input image. Subclasses should override this method to efficiently support streaming.

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.

virtual OutputPixelType itk::ImageBoundaryCondition< TInputImage, TOutputImage >::GetPixel ( const IndexType &  index,

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 value is determined according to the boundary condition type.

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