一種快速提取人臉中心點(diǎn)的方法

針對(duì)安防環(huán)境下監(jiān)控系統(tǒng)的實(shí)時(shí)性要求，本文提出了一種基于膚色分割和人體特征相
結(jié)合的快速人臉檢測(cè)方法。首先利用膚色信息對(duì)彩色圖像進(jìn)行膚色區(qū)域的分割，然后根據(jù)人體的幾何特征進(jìn)行迭代尋優(yōu)求取人臉的中心。實(shí)驗(yàn)結(jié)果證明，所求出的中心可以適用于要求。

A Rapid Method for Face Center Extraction Liu Jun-wei，F(xiàn)an 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.
Key words: skin segmentation; human body characteristic; face center
