#include <itkImageRegion.h>
An image region represents a structured region of data.
ImageRegion is an class that represents some structured portion or piece of an Image. The ImageRegion is represented with an index and a size in each of the n-dimensions of the image. (The index is the corner of the image, the size is the lengths of the image in each of the topological directions.)
