* \brief Extract a region of interest from the input image
* or convert between itk::Image and RLEImage (a custom region can be used).
*
* This filter produces an output image of the same dimension as the input
* image. The user specifies the region of the input image that will be
* contained in the output image. The origin coordinates of the output images
* will be computed in such a way that if mapped to physical space, the output
* image will overlay the input image with perfect registration. In other
* words, a registration process between the output image and the input image
* will return an identity transform.
*
* The region to extract is set using the method SetRegionOfInterest.
