#include <itkRegion.h>
A region represents some portion or piece of data.
Region is an abstract class that represents some portion or piece of a DataObject. A region is used by the pipeline when processing just a portion of the data, either because 1) memory limits dictate that the pipeline cannot fit the entire dataset into memory; 2) the user has requested that only a piece of the dataset is to be processed; or 3) parallel (multi-threaded) processing of the data is required.
There are two types of regions in itk: a structured region that specifies a rectangular piece of an image (ImageRegion), and a unstructured region that specifies piece i of N total pieces (MeshRegion). Depending on the filter (its input and output types, and its position in the pipeline), ImageRegion or MeshRegion will be used to describe the region.
Region is a light-weight object and not reference counted. This means that is behaves differently than ITK classes that are reference counted. For example, smart pointer access is not provided, and the (subclasses') constructor, destructor, copy constructor and operator= are all public.

Methods invoked by Print() to print information about the object including superclasses. Typically not called by the user (use Print() instead) but used in the hierarchical print process to combine the output of several classes.
Reimplemented in itk::ImageIORegion, and itk::TemporalRegion.
