Evaluation of Algorithms for the Determination of Color Gamut Boundaries

p d i bstract. Several techniques for the computation of gamut boundries have been presented in the past. In this article we take an n-depth look at some of the gamut boundary descriptors used when erforming today’s gamut mapping algorithms. We present a ethod for evaluating the mismatch introduced when using a decriptor to approximate the boundary of a device gamut. First, a isually verified reference gamut boundary is created by triangulatng the gamut surface using a device profile or a device characterzation model. The different gamut boundary descriptor techniques re then used to construct gamut boundaries based on several sets f simulated measurement data from the device. These boundaries re then compared against the reference gamut by utilizing a novel oxel based approach. Results from experiments using several amut boundary descriptors are presented and analyzed statistially. The modified convex hull algorithm proposed by alasubramian and Dalal performs well for all the different data ets. © 2010 Society for Imaging Science and technology.
