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.

Abstract
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.
