Evaluation of Gamut Mapping Algorithms in different Uniform Colour Spaces

Abstract

Gamut mapping is an important component in colour management and has drawn much attention in the last decades. However, previous researches mainly focused gamut mapping algorithms (GMAs) and paid little attention to the uniform colour space (UCS) where gamut mapping was taken place. In this paper, two new GMAs were proposed and compared with other commonly adopted GMAs. Two specific UCSs, i.e. CAM16-UCS and J z a z b z were tested by a psychophysical experiment to verify their impact on the mapping performance. Experimental results show that a newly proposed GMA based on vividness perception performed well and J z a z b z is a promising UCS for gamut mapping.
