WitrynaRegardless of the influence of the scene illumination, the human visual system can recognize object colors through its ability known as color constancy [].In the image processing pipeline of almost every digital camera, there is also a part dedicated to computational color constancy [].It first estimates the scene illumination and then … WitrynaIn this paper, we show that it is possible to outperform gamut mapping with a statistical approach, by using appropriate probability models with the appropriate statistical …
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 … WitrynaIn his paper we introduce two improvements to the threedimensional gamut mapping approach to computational colour constancy.
