In this paper we present an RGB to XYZ transformation method based on a pattern search optimization algorithm. Whatever strategy is adopted to initialize the color transformation, our method is able to optimize it in order to minimize the color error on a given training set, also taking into account a color mapping constraint. We report experimental results on simulated and real data sets showing that our method significantly outperforms existing ones.
