摘　　要：提出一种简明的,快速的人脸偏转检测的方法。在该算法中,采用RBG肤色检测人脸,利用肤色的聚类性,基于肤色分割的人脸检测具有稳定性,效果好等特点,从而提出了基于色度信息的投影直方图概念,并依据人脸的几何形状特征标定人脸区域,从而检测出人脸的偏转幅度。实验证明,该算法对于人脸的旋转,表情变化都能适用,具有相对的稳定性,能够快速的检测人脸偏转结果。This paper presents a simple,rapid detection method of face deflection.This algorithm adopts the complexion of RGB to detect the face.It is uses the character of the complexion＇s clustering,and the face detecting which bases on the complexion dividing have the features of stability and high effectiveness.So it poses a concept of projection which bases on chrominance information,and then fix the face-like regions according to the geometric shape of facial features,so that the human face deflection extent can be detected.The experiment proves that the algorithm is applies to the face＇s whirling and expression＇s change.It has the relative stability,and could detect the result of the face＇s excursion rapidly.
