Research of the Weighing Coefficient and Acceptability Threshold of Three Different Color-Difference Formulas
The purpose of this research was to improve the uniformity of color-difference equations. Twentyobservers performed a pass-fail color tolerance experiment for 17 color centers and approximately 259 colorsamples, which have different chromatic. We measured CIELab color values of all colors. Multiple linear regressionequation can be used to calculate the best weighting coefficient of CIE94、CMC and CIE2000. Wegot the acceptable threshold of each color center with cumulative frequency statistics method. The improvedresults of color-difference formulas about the same color and the same color of different saturation were compared.
