Evaluation of Device Color Gamut Description Algorithms

Abstract:

A well performed gamut boundary description (GBD) algorithm is the foundation of color gamut mapping and it is also a guarantee for color management to acquire a good results. In order to get a more accurate color gamut boundary and have a intuitive view of what can be reproduced by the device, several GBDs have been presented in the past, since there is not exist a widely accept GBD evaluation method, it is difficult to choose which to use in color gamut mapping and color gamut visualization. In this paper, we propose a device GBD evaluation method based on volume rendering technique to evaluate the current presented GBD algorithms. First a dense sample of device color space is made, then those data is converted into CIELAB color space through the device ICC profile using colorimetric rendering intent, the data is then processed using volume rendering technique into voxels, those voxels which contain all the color the device can reproduced is considered as the reference gamut. Finally the device color gamuts constructed by different GBD algorithms using converted data are compared with the reference gamut using the new gamut mismatch indice.
