Abstract
Transformation model of RGB color space to CIE LAB color space was established by using support vector regression (SVR). CIE DE2000 and CIE 1976L*a*b* color-difference formulas were used in calculation of accuracy of the model. Based on CIE DE2000 color-difference formula, the average, maximum and minimum color differences of text set are 2.6597, 5.2194 and 0.2065. Based on CIE 1976L*a*b* color-difference formula, the corresponding results are 2.8656, 5.8791 and 0.3769. The results showed that color differences are basically the same by using CIE DE2000 color-difference formula and CIE 1976L*a*b* color-difference formula which accord with the accuracy of the color scanner characterization. Therefore, CIE DE2000 color-difference formula can be used in the management of scanner characterization.
