Improving gamut mapping color constancy

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 … 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
