Research on Color Space Uniformity Based on New Color Appearance Model CAM16
In this study, the color space uniformity of a new color appearance model CAM16 is analyzed and evaluated. The vision uniformity of the color space of the CAM16 model is insufficient, which will affect the cross-media color reproduction accuracy and result in color difference with respect to the same colors under different viewing conditions. Therefore, a BFD color difference dataset is used to optimize the model for ensuring visual uniformity, and an optimized color appearance model CAM16-J'a'b' is proposed. Subsequently, the optimized color space is subjected to a uniformity test based on international Munsell color system. The results denote an improvement in the uniformity of the optimized color space, thereby providing a reference for cross-media color reproduction research.
