Abstract
A color image is locally discoloured in the vicinity of edges. The edges extend, for example, between a superposed foreground and a background in a computer-generated image, but also between different regions in natural images which are processed, for example, in a television receiver. Consequently, the edges are perceived as being sharper upon display.
