肤色信息在人脸检测中的应用

基于肤色信息的人脸检测方法能快速获得所有可能的候选人脸，把经过光线补偿处理后的彩色图像从RGB转换到YCbCr色彩空间，根据实验获得的最佳阈值进行肤色分割，快速获得所有可能的候选人脸。对候选人脸作形态学处理及人脸区域标定，最终确定人脸区域。实验结果表明，基于肤色的人脸检测方法能快速的区分人脸区域和背景区域，将人脸区域标定在一个白色的矩形框内，具有良好的检测效果。

Application of Skin Color Information in Face Detection

Face detection method which base on skin color information can quickly obtain all the possible candidate faces.In this paper,the color images after light compensation are changed from RGB to YCbCr color space.Based on experiment,the best threshold is obtained.Then skin color segmentation is carried out and obtains all the possible candidate faces quickly.Morphologically process candidate faces and locate the face regions,and finally find the face regions.The result of experiment shows that the face detectio...
