Abstract: To solve gamut mismatch problems in color reproduction across different devices, a new color gamut mapping algorithm is proposed. First, by analyzing the subjective assessment process, a gamut mapping evaluation model via human vision system is defined, and their consistence is proved. Then under the guidance of the model and by considering both image colors and image spatial characteristics, a divide and conquer scheme is employed and a mapping fusion model is constructed to implement the method. Experiments show that the proposed algorithm has obvious advantage over traditional ones, especially in color difference and image details.
