人脸检测算法中对肤色分割效果的加强

In this paper, the theory of face detect algorithm based on skin color and a relevant system configuration are introduced. It’s experimented with skin color model in YCbCr color space by Anil K. Jain etal. , which segments skin and non-skin regions according to the cluster on hue plane. Another, A new method is addressed to pre-treat the luminance of images by high-frequency emphasis filter, which avoids the noise of background objects with the similar color as skin, and reinforce to segment facial regions. The new pretreatment increases the accuracy of face detect system.
