The paper [9] pointed out that in the Y-U color
space, the skin color in the U-V plane distributes in a

stored mode and addresses in the data buffer, this paper
selected YUV color space to analysis clustering and
establishment skin color model. We randomly selected
36 image include different lighting backgrounds,
different postures, and covering different age groups as
a group of images. Following these steps to establish a
color model:
