Comparison of the CIELab and CIEDE2000 color difference formulas

摘要

Statement of problem. Many color specification systems and color differences have been proposed to improve the correlation between color measurement and visual perception. Although color differences can be quantified using either the CIELab formula (Delta E-ab*) or the recently introduced CIEDE2000 formula (Delta E00), which captures the perceived color difference better is unknown.
