Detailed Description

template<class TScalarType, unsigned int TDimension>
class itk::watershed::Boundary< TScalarType, TDimension >

A data object for used by watershed segmentation process objects in streaming applications. A ``boundary'' represents the single-pixel wide surface of an image chunk. This class is used to store information needed to resolve processing at chunk boundaries after data streaming of the watershed segmentation algorithm.
This is an itkDataObject. It contains a matrix of ``faces'' of an N-dimensional hypercube. A chunk of a volume with $ N $ dimensions has $ 2N $ faces of dimension $ N-1 $. Some examples: A 2-dimensional image has 4 faces that are lines. A 3-dimensional image has 6 faces that are planes. A 4-dimensional image has 8 faces which are cubes. Faces are indexed as $ N $ sets of pairs $ (low, high) $.
