#include <itkNeighborhood.h>
A light-weight container object for storing an N-dimensional neighborhood of values.
This class serves as the base class for several other Itk objects such as itk::NeighborhoodOperator and itk::NeighborhoodIterator. Its purpose is to store values and their relative spatial locations.
A Neighborhood has an N-dimensional radius. The radius is defined separately for each dimension as the number of pixels that the neighborhood extends outward from the center pixel. For example, a 2D Neighborhood object with a radius of 2x3 has sides of length 5x7. Neighborhood objects always have an unambiguous center because their side lengths are always odd.
