Abstract: A lot of colors similar as skin color exist in nature，they bring many difficulties to detect human face color.This paper presents a skin color detecting method that it combines circular clustering distribution of Cg-Cb color space with a parallelogram clustering distribution of Cg-Cr color space.The experimental results show that under complicated background,this method is simple and the velocity is fast，it also can wipe off most of the non-skin color and reserve the skin color perfectly.
