RECENT PROGRESS IN REPAIRING CIECAM02
While CIECAM02 enjoys its popularity in widely used in theoretical research and industrial applications, some problems are also identified. Unexpected computational failure is one of the important problems concerned by the cross-media colour reproduction industry. In this paper progress towards repairing the CIECAM02 is reviewed, which includes the several proposals for replacing the CAT02 matrices under the same structure as the original CIECAM02 in the past and the newest development in changing the structure of the CIECAM02. It was found that all the extension proposals under the same structure of the original CIECASM02 have one thing in common, that is at the expense of losing predicting accuracy compared with the original. However, the latest development in changing the structure of the CIECAM02 results in a very promising proposal. In the latest proposal, the adaptations of the colour and luminance of the illuminant are made in one space rather than in the two different spaces in the original CIECAM02. The new proposed version not only solves all the problems concerned related to the CIECAM02, but also performs equally well or better than the original in predicting the visual corresponding colour datasets and the colour appearance datasets. Furthermore, it is simpler than the original.
