Gamut mapping using variable anchor points

Recently, a variety of imaging devices are being used to represent electronic color images the reproduced color, however, is different from the original color because of the difference of producible colors on the devices. The range of producible colors offered by a device is referred to as its gamut. In his paper, a gamut-mapping algorithm (GMA) is proposed that can maintain device-independent color. Categorized as a parametric GMA, this algorithm utilizes variable anchor points to both reduce a sudden color change on the gamut boundary of the printer and to maintain a uniform color change during the mapping process. Accordingly, the proposed algorithm can reproduce high quality images with low-cost color devices.
