实现人脸检测 主要是针对裸露肌肤检测，从而实现对色情图像的过滤，用了rgb，hsv，ycrcb，纹理检测等多种方法，可以运行，效果不错-Implementation of face detection is mainly directed against the bare skin testing, in order to achieve the filtering of pornographic images, using the rgb, hsv, ycrcb, texture detect

基于rgb空间到ycrcb空间的非线性变换来进行肤色的识别-use ycrcb to regonice the skin

我的工程用的红外摄像头。如果你用RGB摄像头，要将Segmentation部分替换，可以参考网上的HSV肤色检测程序。(My project uses an infrared camera. If you want to replace Segmentation with a RGB camera, you can refer to the HSV skin detection program on the internet.)
