。基于颜色的系统可以在不同的视角中均能检测到人脸，不受人脸姿态变化的影响。根据颜色进行人脸检测的问题在于人所感知到的颜色与到达视网膜的光线的频率并不是一样的。通过对人脸图像做二值化，统计像素比例信息。得到人脸识别结果.这里通过对人脸图像打上网格，对区域块图像做二值分析，通过像素比例来做处理。进而得到人脸区域。-. Color-based system could be detected in a different perspective to the face, not the face attitude change. According to the color of the face detection problem is that the frequency of the perceived color of the light reaches the retina is not the same. Done by the human face image binarization, the statistical pixel ratio information. Face recognition results here by playing on the face image grid, do binary analysis of the regional block image by pixel ratio do processing. Then get the face region.
