说明：  matlab区域填充的具体算法及演示，绝对原创(the algorithm of fill an origin used matlab)

先对图片进行灰度处理，然后进行高斯滤波，最后得到边缘特征点。(First deal with gray-scale pictures, and then carry out Gaussian filter, and finally get the edge feature point.)

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(Written using Matlab projection extraction lips input image must be provided for the size of face)

图像匹配，通过选定模板图像和要要匹配的图像，在要匹配的图像中用红色方框标记处匹配的区域。(Image matching, through the selected template image and want to match the image, to match the image using the red mark at the box matches the area.)

说明：   针对雾天下拍摄图像的退化现象，远景部分是一块灰度分布比较集中且接近天空亮度的区域，而近景部分可以分辨，其灰度分布比较分散。提出了一种基于遗传算法阈值分割的雾天图像增强方法；该方法首先用遗传算法求出近远景的分割阈值将图像分割[1]出来，然后对两个部分分别进行清晰化处理。(make the picture clear)
