利用该函数可以对图像进行仿射变换，是不错的matlab源代码(Function can make use of the image affine transformation, is a good source code matlab)

image processing for hand guesture

matlab代码实现的retinex图像增强(retinex image enhancement matlab code)

图像金字塔分解，输入一幅图像，以及需要分解的层数，可以输出图像的金字塔分解(Image pyramid decomposition)

实验图像数据曲线描绘刻画，进行数据拟合：高斯拟合，平滑处理(gaussian nihe)

K-SVD的工具箱，使用非常简单，直接运行demo。有助于学习K-SVD，对初学者非常有用。(K-SVD Toolbox, easy to use and it is very useful for beginners.)

说明：  基于模糊C均值的快速点云的聚类分析代码，可用于模糊聚类(Clustering analysis code of fast point cloud based on fuzzy c-means can be used for fuzzy clustering)

用MATLAB对两幅图片进行图像匹配,程序运用了两种匹配算法:1.sad算法2.ssad算法3.的采用界面输入输出方式.(MATLAB to two picture image matching, and the program using the two matching algorithms: 1. Sad algorithm 2.Ssad algorithm of the input and output interface mode.input/output mode.)

说明：  实现直接序列扩频水印的嵌入与提取。基于待嵌入消息生成二进制水印序列,生成扩频码，用消息序列调制生成水印序列。依次处理灰度图像的每一个载体图像像素，根据相应位置 水印序列完成嵌入修改。(Realize the embedding and extraction of direct sequence spread spectrum watermark. The binary watermark sequence is generated based on the message to be embedded, the spread spectrum code is generated, and the watermark sequence is generated by message sequence modulation. Each carrier image pixel of gray image is processed in turn, and the embedding modification is completed according to the corresponding position watermark sequence.)

PLSA源码，并附有PLSA理论在图像自动标注中的应用，有几篇具有代表性的论文，论文中讨论了PLSA的改进并应用在图像处理中。(PLSA source code, with PLSA theory in automatic image annotation application, some of the representative papers, thesis discusses the PLSA improvement and application in image processing.)
