Optimizing Color-Difference Equations and Uniform Color Spaces for Industrfial Tolerancing
Euclidean distances calculated for CIE recommended color spaces such as CIELAB and CIECAM02 have limited correlation with visual color-tolerance datasets. The RIT-DuPont and Qiao datasets were used to demonstrate such limitations. A weighted color-difference equation was optimized to improve the performance of CIECAM02. This equation was used to derive a Euclidized CIECAM02 by integrating line elements. The coordinates of CIECAM02 were also rotated to improve visual uniformity about midgray stimuli. PF/3, maximum disagreement, and an F-test were used to evaluate performance. All of these distance measures had equivalent performance to CIEDE2000, indicating future opportunities for color spaces with improved performance
