Abstract
In this paper, a new chromatic adaptation method called maximum color separation (MCS) is described. In the new method, the assumption is that image gamut reaches its maximum when under white illuminant. The essence of the MCS lies in the rigid theoretical framework of the coincidence of the chromatic gamut centroid with the coordinate of the ideal white illuminant when the area of a chromatic gamut is maximized. Inversely, the MCS explains the theoretical structure of the assumption. The MCS has strong similarity with the gray world, but essential differences in adaptation structures are shown. Experimental results using real images show the efficiency of the proposed method.
