静态灰度图像中的人脸检测方法综述

Survey on Face Detection Methods in Gray-level Still Images

1.引言在日常生活中,人的脸部特征给我们提供了大量丰富的信息.对于人脸的研究因其在身份验证、档案管理和可视化通讯等方面的巨大应用前景,备受研究者关注,成为一个非常活跃的研究领域.很多人脸研究工作都是假定图像中的人脸已经被检测和定位.而为了设计出自动人脸识别系统,快速而高效地检测人脸是需要解决的一个关键问题.

In recent twenty years,the technique of face detection and face recognition,as one of the important research area of computer vision and image understanding,attracts more and more attention. In general,face detection in gray-level still images is more difficult than that in color images. Therefore this paper briefly surveys this area and indicates some issues for exploration.
