可以用于图像分割的KNN分类器，简单好用！(knn classification)

用于计算均匀圆球的mie散射，matlab 程序，可计算散射系数，消光截面等(It is used to calculate the Mie scattering of uniform spheres. The matlab program can calculate the scattering coefficient and extinction section.)

BM3D去噪算法的实现和相关文档，很好的去噪算法(Image and video denoising by sparse 3D transform-domain collaborative filtering Block-matching and 3D filtering (BM3D) algorithm )

数字图像抠图源代码,是由一个外国人写的，非常好用，我希望能和大家一起分享(digital image matting matlab code written by a foreigner,it is very useful and I would like to share with everyone)

说明：  利用基于直方图的自适应阈值方法实现分割前景与背景a）设定三个不同阈值，直接观察分割结果； b) 利用统计直方图，得到一个自适应的阈值.(The segmentation foreground and background a are realized by using the histogram based adaptive threshold method, and three different thresholds are set, and the segmentation results are observed directly. B) a adaptive threshold is obtained by using the statistical histogram.)

自己写的一种查找图像边缘的方法，效果还不错(a way to find the edge of a picture by myself, and it can reach good result)

视频修复的效果非常的好，而且速度还挺快的，挺好用的，可以试试(video inpainting)

LPQ——TOP特征提取源码及其应用，能够很好提取动态的表情特征，可以用在表情识别以及姿态检测上。(LPQ- TOP feature extraction and its application source code, can be a good dynamic expression feature extraction, can be used on face recognition and gesture detection.)

Diff-rankboost算法,代码功能是产生图片美学质量之间相互的排名差距，便于进一步的进行训练和测试(Diff-rankboost algorithm, code function is to produce the ranking of mutual aesthetic gap between picture quality, ease of further training and testing)

图像处理中的一些常用代码，包括：腐蚀操作 开启和闭合操作 形态学边界提取 形态学骨架提取 直接提取四个顶点坐标(Some of the commonly used image processing code, including: Opening and closing operation of corrosion morphology boundary extraction morphological skeleton extraction to extract four vertex coordinates)
