Abstract

This paper presents a new technique based on anisotropic diffu-sion
for segmenting color images. This operation is accomplished
through two independent anisotropic diffusion processes: one in-volving
only the chromatic information, conveniently embedded in
a complex function, and the other affecting the lightness informa-tion.
The results of the two diffusions are separately segmented
and their combination allows the color image to be eventually par-titioned.
We report on some experimental results verifying the ef-fectiveness
of such a technique.
