用Matlab写的投影法提取嘴唇 输入图像必须是规定大小的人脸

基于GVF的SNAKE算法，应用于红外人脸分割，用matlab编写的-SNAKE the GVF-based algorithms, used in infrared face segmentation, prepared by matlab

在YCbCr通道上，对人的嘴唇的寻找，通过大量数据样本得到的嘴唇颜色区域，效果不错，这个程序只是在静态图片里寻找，对做嘴形识别的人有帮助-Channel in the YCbCr on the lips of people search through a large amount of data samples to be the color of the lip region, the effect is true that this procedure only to find a sta
