Improving gamut mapping color constancy
Witryna26 cze 2000 · The University of Arizona Abstract and Figures In his paper we introduce two improvements to the three- dimensional gamut mapping approach to … 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 …

It is therefore well-suited for gamut mapping implementations. ICtCp

By using white (W) pixels instead of G pixels, the RWB CFA provides high-sensitivity imaging and an improved signal-to-noise ratio compared to the Bayer CFA. …
