由于YcgCr颜色空间好的聚类性.提出一种在YCgCr颜色空间的人脸检测,首先肤色在CgCr颜色空间进行投影,对像素点区域进行拟合,初步去除图像中的非肤色,得到肤色第一次分割的图像,实验证明这种拟合可以起到好的去除非肤色像素的作用.然后把YCgCr颜色空间作为肤色模型建立彩色空间,用高斯模型在已提取的图像上进行人脸检测.实验证明在对CgCr空间拟合的基础上,再运用高斯模型进行人脸检测,该算法提高了人脸检测的速度,并且有较高的检测率和较低的漏检率.
由于YcgCr顏色空間好的聚類性.提齣一種在YCgCr顏色空間的人臉檢測,首先膚色在CgCr顏色空間進行投影,對像素點區域進行擬閤,初步去除圖像中的非膚色,得到膚色第一次分割的圖像,實驗證明這種擬閤可以起到好的去除非膚色像素的作用.然後把YCgCr顏色空間作為膚色模型建立綵色空間,用高斯模型在已提取的圖像上進行人臉檢測.實驗證明在對CgCr空間擬閤的基礎上,再運用高斯模型進行人臉檢測,該算法提高瞭人臉檢測的速度,併且有較高的檢測率和較低的漏檢率.

Due to the clustering is excellent in a color space YCgCr.This paper provides a way of face detection in a color space YCgCr.Firsfly,skin colors are projected in a color space CgCr and the fitting of distribution is carried through in order to wipe off a part of non skin color and gain the intersected image for the first time.Experimental results indicate that this fitting of distribution can reduce the great mass of processing pixels of non-skin color.Then this paper puts Color Space YCgCr as the color model to build a color space and use Gauss model to detect human face on a base of the intersectecl image.Experimental results indicate that Gauss model to detect human face on a base of fitting of distribution in CgCr color space can improve the speed of face detection and have upper detecting ratio.This way also has upper detection ratio and lower ratio of missing detection and low ratio of false detection.
