Detailed Description

template<class TImageType>
class itk::ImageBoundaryCondition< TImageType >

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.

Extract information from the image type

template<class TImageType>
virtual PixelType itk::ImageBoundaryCondition< TImageType >::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.

Implemented in itk::ConstantBoundaryCondition< TImage >, itk::PeriodicBoundaryCondition< TImage >, itk::ZeroFluxNeumannBoundaryCondition< TImage >, itk::ConstantBoundaryCondition< InputImageType >, itk::ZeroFluxNeumannBoundaryCondition< MovedGradientImageType >, itk::ZeroFluxNeumannBoundaryCondition< FixedImageType >, itk::ZeroFluxNeumannBoundaryCondition< InputImageType >, and itk::ZeroFluxNeumannBoundaryCondition< FixedGradientImageType >.

template<class TImageType>
virtual PixelType itk::ImageBoundaryCondition< TImageType >::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.

Implemented in itk::ConstantBoundaryCondition< TImage >, itk::PeriodicBoundaryCondition< TImage >, itk::ZeroFluxNeumannBoundaryCondition< TImage >, itk::ConstantBoundaryCondition< InputImageType >, itk::ZeroFluxNeumannBoundaryCondition< MovedGradientImageType >, itk::ZeroFluxNeumannBoundaryCondition< FixedImageType >, itk::ZeroFluxNeumannBoundaryCondition< InputImageType >, and itk::ZeroFluxNeumannBoundaryCondition< FixedGradientImageType >.
