Abstract

A new target for defining media gamut boundaries is described. The use of measured gamut boundary data using provided by this target is capable of improving the accuracy of gamut boundary predictions in both device model and gamut mapping computations. The accuracy of existing methods of calculating gamut boundaries can be improved by use of an enlarged gamut boundary training set to derive the gamut boundary descriptor. An alternate, computationally simple, method of calculating gamut boundary intersections is described, and its performance in calculating such intersections and in media mapping is described. There is good agreement between this method and FSLGB in predicting boundary intersections if the same data is used to derive the gamut boundary descriptor. The gamut boundary target described in this paper is thus proposed as a means of obtaining greater information about media gamut boundaries.
