| Abstract: | ome problems in CIECAM02 that have been identified and the solutions are reviewed.Those problems include mathematical failure for calculating lightness,yellowblue problem and purple problem that result in mathematical instabilities,a gamut mapping,HPE matrix and backward model when the CIECAM02 is used in an ICC workflow.It is showed that proposed solutions need to be verified by various applications and new solutions need to be presented.Color appearance models are still at the process of development. |
