Skin color detecting based on YCgCb and YCgCr color space

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.
