Locating Unique Hues under mixed illumination conditions in CIECAM02

摘要

Unique hue settings of 185 observers under two room lightingrnconditions were used to evaluate the accuracy of mixed chromaticrnadaptation transform models of CIECAM02 in terms of unique huernreproduction. The current CIE recommendation for mixedrnchromatic adaptation ratio produced unsatisfying performance inrnterms of perceptual hue shifts in CIECAM02. Using our large datarnset of unique hue data as a benchmark, an optimised parameter isrnsuggested for chromatic adaptation under mixed illuminationrnconditions that produces more accurate results in unique huernreproduction.
