WitrynaThe gamut mapping algorithm provides among the best results in color constancy experiments [3]. Finlayson et al. [12] improve the gamut mapping algorithm by restricting the transformations to be plau- sible, meaning that only illuminants are allowed which correspond to existing illuminants. WitrynaThe IPT color appearance model excels at providing a formulation for hue where a constant hue value equals a constant perceived hue independent of the values of lightness and chroma (which is the general ideal for any color appearance model, but hard to achieve). It is therefore well-suited for gamut mapping implementations. ICtCp trustmark insurance lake forest https://lyonmeade.com
