发明名称 METHOD AND SYSTEM FOR PARTITIONING AND MAPPING COLOR GAMUTS BASED ON ONE-ONE AND ONTO MAPPING FUNCTION
摘要 A method and system for mapping color gamuts based on one-one and onto mapping function in order to create an invertible transform is disclosed. A hue leaf associated with at least two arbitrary color gamuts can be defined utilizing a vector math function and a most saturated point with respect to each hue leaves can be determined. A safe area relative to an intersection point can be estimated by approximating the most saturated point in both hue leaves. An upper hull and a lower hull associated with the hue leaves can be continuously sub-divided with an equal number of sections by constructing one or more vectors. An appropriate section for computing a vector relationship in the color gamut can be determined in order to map the color gamuts based on the continuous, one-one and onto function thereby creating an invertible transformation.
