%description
Fast image processing for images in up to 4 dimensions (two spatial
dimensions, one time/depth dimension, one colour dimension). Provides most
traditional image processing tools (filtering, morphology,
transformations, etc.) as well as various functions for easily analysing
image data using R. The package wraps 'CImg', <http://cimg.eu>, a simple,
modern C++ library for image processing.
