document: Generalized spatio-chromatic diffusion A framework for diffusion of color images is presented . The method is based on the theory of thermodynamics of irreversible transformations which provides a suitable basis for designing correlations between the different color channels . More precisely , we derive an equation for color evolution which comprises a purely spatial diffusive term and a nonlinear term that depends on the interactions among color channels over space . We apply the proposed equation to images represented in several color spaces , such as RGB , CIELAB , Opponent colors , and IHS
