Applying Mixed Adaptation to Various Chromatic Adaptation Transformation (CAT) Models
In 1998, a Technical Committee 8-04 was formed in CIE/Division 8, "to investigate the state of adaptation of the visual system when comparing soft-copy images on selfluminous displays and hard copy images viewed under various ambient lighting conditions." Several past studies indicated that applying mixed adaptation to the chromatic adaptation transformation improves the prediction of color appearance of CRT monitor viewed under mixed illumination. CIE/TC1-52 has been investigating the chromatic adaptation transforms. Most of the color appearance models in early 90's used Hunt-Pointer-Esteves (HPE) transformation. In late 90's, Luo et al.'s experimental results indicated that Bradford (BFD) transformation was superior, and BFD transformation was then adopted in CIECAM97s. Recently, Thornton suggested optimum RGB primaries are at 450-533-611nm. It was of great interest for the CIE/TC8-04 members to test other chromatic adaptation transformation in S-LMS mixed c...
