Performance of CIEDE2000 color difference models for the RIT-DuPont dataset
It has been found that one of the four experimental datasets employed for the development of the CIEDE2000 color difference formula, the RIT-DuPont dataset, was not properly used. We analyze the performance of the CIEDE2000 formula for the revised RIT-DuPont dataset, and for the combined (COM) weighted dataset employed in the development of CIEDE2000. This work complements our previous research on the relative significance of the terms in the CIEDE2000 and CIE94 color-difference formulas. For the revised RIT-DuPont dataset, CIEDE2000 is not significantly better than CIE94 (95％ confidence level).and only the chroma and hue corrections of CIEDE2000 are statistically significant. However, for the COM weighted dataset which includes the revised RIT-Dupont dataset, CIEDE2000 improves CIE94 with statistical significance at a 95％ confidence level, and each one of the 5 corrections introduced by CIEDE2000 are statistically significant at this confidence level. These results call for a comparative study of the four datasets employed at CIEDE2000 development.
