Analysis of Five Sets of Color Difference Data

摘要

In a systematic optimization process five sets of recent color difference data have been analyzed for com- monalities. Adjustment of the X tristimulus values and ap- plication of a systematic surround dependent S_L function was found to be beneficial in all cases. Other modifications of the CIE94 color-difference formula were found to bring improvements only in some cases and may be spurious. Application of what seem to be nonsystematic scale factors In a range of 0.78-1.38 improve correlation between cal- Culated and visual color differences in all cases
