Detailed Description

template<class TInputImage, class 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.

Member Function Documentation

template<class TInputImage, class TOutputImage = TInputImage>

virtual RegionType itk::ImageBoundaryCondition< TInputImage, TOutputImage >::GetInputRequestedRegion	(	const RegionType &	inputLargestPossibleRegion,
		const RegionType &	outputRequestedRegion
	)		const `[inline, virtual]`

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:

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.

template<class TInputImage, class TOutputImage = TInputImage>

virtual const char* itk::ImageBoundaryCondition< TInputImage, TOutputImage >::GetNameOfClass ( ) const [inline, virtual]

Runtime information support.

Definition at line 85 of file itkImageBoundaryCondition.h.

template<class TInputImage, class TOutputImage = TInputImage>

virtual OutputPixelType itk::ImageBoundaryCondition< TInputImage, TOutputImage >::GetPixel	(	const IndexType &	index,
		const TInputImage *	image
	)		const `[pure virtual]`

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:

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

template<class TInputImage, class TOutputImage = TInputImage>

virtual OutputPixelType itk::ImageBoundaryCondition< TInputImage, TOutputImage >::operator()	(	const OffsetType &	point_index,
		const OffsetType &	boundary_offset,
		const NeighborhoodType *	data,
		const NeighborhoodAccessorFunctorType &	neighborhoodAccessorFunctor
	)		const `[pure virtual]`

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

template<class TInputImage, class TOutputImage = TInputImage>

virtual OutputPixelType itk::ImageBoundaryCondition< TInputImage, TOutputImage >::operator()	(	const OffsetType &	point_index,
		const OffsetType &	boundary_offset,
		const NeighborhoodType *	data
	)		const `[pure virtual]`

Returns a value for a given out-of-bounds pixel. The arguments are the phantom pixel (ND) index within the neighborhood, the pixel's offset from the nearest image border pixel, and a neighborhood of pointers to pixel values in the image.

template<class TInputImage, class TOutputImage = TInputImage>

virtual void itk::ImageBoundaryCondition< TInputImage, TOutputImage >::Print	(	std::ostream &	os,
		Indent	i = `0`
	)		const `[inline, virtual]`

Utility for printing the boundary condition.

Reimplemented in itk::ConstantBoundaryCondition< TInputImage, TOutputImage >, and itk::ConstantBoundaryCondition< InputImageType >.

Definition at line 91 of file itkImageBoundaryCondition.h.

template<class TInputImage, class TOutputImage = TInputImage>

virtual bool itk::ImageBoundaryCondition< TInputImage, TOutputImage >::RequiresCompleteNeighborhood ( ) [inline, virtual]

Tell if the boundary condition can index to any location within the associated iterator's neighborhood or if it has some limited subset (such as none) that it relies upon. Subclasses should override this method if they can safely limit indexes to active pixels (or no pixels).

Reimplemented in itk::ConstantBoundaryCondition< TInputImage, TOutputImage >, and itk::ConstantBoundaryCondition< InputImageType >.
