Baseline Gamut Mapping Method for the Perceptual Reference Medium Gamut

摘要

A need for a baseline algorithm for mapping from the 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 candidate algorithm is also described.
