Color Constancy Using Single Colors

This work investigates if the von Kries adaptation can be generalized to deal with single colored patches. We investigate which colored patches can give statistically equivalent performance to a white patch for von Kries adaptation. The investigation is then extended to couples of colors, and the analysis of the characteristics of the colors forming the couples is carried out. We focus here on single and couples of colors since common objects and logos are usually composed by a small number of colors.
