摘　　要：提出了在复杂背景、不同光照条件下层次式的彩色图像的人脸检测算法。首先,利用颜色补偿技术在YCbCr颜色空间对彩色图像进行肤色分割,选出类似皮肤的区域。然后,通过人脸椭圆形状来检测人脸候选区域。最后,构造眼睛和嘴巴的映射来成功检测出人脸。We have proposed a hierarchical face detection algorithm in color images under complex backgrounds and varying lighting conditions.First,an efficient color compensation method for skin color segmentation has been introduced in YCbCr color space to select skin-like regions.Then,the shape of ellipse has been utilized to locate face candidates.Finally,eye and mouth maps have been constructed to detect faces successfully.

关 键 词：人脸检测 肤色检测 脸部特征映射
