Improving gamut mapping color constancy

WitrynaThe work is founded on previous gamut mapping solutions to the problem which solve for a scene illuminant by determining the set of diagonal mappings which take image … WitrynaFigure 1: Illustration of the basic idea of gamut mapping color constancy. Once the set of possible maps has been computed, an important second stage of the algorithm is to choose a solution from the feasible set. The original method was to choose the mapping which maximized the volume of the mapped set.
