Detailed Description

template<typename TScalar, unsigned int TDimension>
class itk::watershed::Boundary< TScalar, 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 \( (low, high) \).
