Gamut mapping for the Perceptual Reference Medium Gamut

A requirement for a baseline algorithm for mapping from the ICC Perceptual Reference Medium Gamut to destination media in ICC output profiles has been identified. Before such a baseline algorithm can be recommended, it requires careful evaluation by the user community. A framework for encoding the gamut boundary and computing intersections with the PRMG and output gamuts respectively is described. This framework provides a basis for comparing different gamut mapping algorithms, and a number of candidate algorithms are also described.
