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 data captured under an unknown light to a gamut of reference colours taken under a … Witrynaconstraint-based methods. Even though our algorithm outperforms gamut mapping on average, there are cases in which gamut mapping provides better estimates, and, in fact, the errors of the two methods are surprisingly uncorrelated. This is an interesting result, because it suggests that gamut mapping exploits image properties which are …

Witrynaelegance of the gamut mapping approach with additional robustness of the image derivatives to deviations of the di-agonal model and diffuse lightning. The paper is organized as follows. In sections 2 and 3, color constancy is defined and the original gamut mapping is explained, respectively. In section 4, the derivative-based The gamut mapping approach to color constancy is, to date, one of the most successful solutions to this problem. In this algorithm the set of mappings taking the image colors recorded under an unknown illuminant to the gamut of all colors observed under a standard illuminant is characterized.

This approach... 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.
