Abstract

Color constancy and chromatic edge detection are fundamental problems in artificial vision In this paper we present a way to provide a visualization of color constancy that works well even in dark scenes where such humans and computer vision algorithms have hard problems due to the noise The method is an hybrid and non linear transform of the RGB image based on the assignment of the chromatic angle as the luminosity value in the HSV space This chromatic angle is defined on the basis of the dichromatic reflection model, having thus a physical model supporting it.
