One way of enhancing color image contrast is to feed back high-frequency spatial information from the saturation component into the luminance component. A new algorithm, which uses a spatially variant measure of salience, is presented. This method offers key improvements to a previous saturation feedback technique. Experimental results confirm that improved color image enhancement is achieved.
