Considering the complexity of the calculation, the
present skin color model uses the two-dimensional skin
color model basically [3-7]. In order to avoid the
influence of the illumination they as far as possible
separate the color component and brightness, the
neglect of brightness caused a certain degree’s missed
in the Practical applications. But the computation of
complete three-dimensional skin color model’s are too
complexity [8], Have restricted its application in
reality
