Optimised Parameters for CIECAM02 Based Upon Surround Size Effect
  DOI :  10.2352/CGIV.2008.4.1.art00011  Published OnlineJanuary 2008

This study investigates the effects of the size and the luminance value of the surround field on colour appearance under various viewing conditions. Ten phases of psychophysical experiments were conducted to obtain visual data assessed by a panel of 10-15 observers. The viewing conditions investigated include two sizes of surround field, three viewing distances, two luminance values of surround and three different sizes of stimuli. The accumulated visual data sets were used to test the CIE colour appearance model, CIECAM02, and the results showed that CIECAM02 gave a satisfactory prediction. Finally, the viewing parameters F, Nc and c in CIECAM02 were optimised to fit colour appearance results under different surround conditions. It was found a very small improvement.
