Preprocessing to CIECAM02 input color with chromatic background

Progress in the Theory Studies of CIECAM02

“…In 2006, Chai Binghua proposed a relatively simple method to preprocess color under chromatic background for CAM02 calculation ,by visual psychophysical experiments. Because of the limitation for time and conditions, the formula's accuracy is still to be improved [5]. In 2007, Ray-Chin Wu studied the simultaneous contrast effect on the CRT monitor, their results are that simultaneous contrast effect have much more effect on changes in brightness ,less in changes of hues, they proposed an improved model ,called CIECAM02-m2,for predicting simultaneous contrast effect.…”
