一种快速提取人脸中心点的方法

针对安防环境下监控系统的实时性要求，本文提出了一种基于肤色分割和人体特征相
结合的快速人脸检测方法。首先利用肤色信息对彩色图像进行肤色区域的分割，然后根据人体的几何特征进行迭代寻优求取人脸的中心。实验结果证明，所求出的中心可以适用于要求。

A Rapid Method for Face Center Extraction Liu Jun-wei，Fan Rui-xia (Department of Automatic Control, School of Information Science and Technology, Beijing Institute of Technology, Beijing,100081) Abstract: Aiming at the real-time requirement of video surveillance system in security and defence environment, a rapid method of face center extraction based on skin segmentation and human body geometry characteristic is proposed. Firstly skin color information is used to segment images into two parts of skin color region and non-skin color region. Then the face center is got according to body geometry characteristic. Experiment result proved that the center obtained by this means meets the requirement.
