COLOR EDGE DETECTORS FOR CONICAL COLOR SPACES

Under very general conditions it can be shown that spaces of color spectra can be equipped with a coordinate system in which the coordinates of all spectra are located in a cone. The coordinates in these systems describe hue-, intensityand saturation-like properties of the color spectra. These spaces carry thus a natural conical geometry. In this paper we investigate edge detection and di usion processes based on these conical coordinate systems in spaces of color spectra. This is done in the framework of the Beltramiow developed by Sochen et. al..
