目前MATLAB里边对于多点计算仿射矩阵普遍采用RANSAC法，但是比较麻烦计算量也相对较大，通过最小二乘法来进行仿射矩阵的估计能够大大提高该效率，所以奉上自己在实验室写的仿射矩阵估计函数，来弥补matlab函数库在这方面的不足。(The MATLAB inside for calculating affine matrix commonly used RANSAC method, but more trouble calculation is relatively large, estimated by the least squares method to the affine matrix can greatly improve the efficiency, so give yourself in laboratory to write the estimated affine matrix function, to compensate for the lack of MATLAB Library in this area.)

HOG（方向梯度直方图）图像特征提取，以lena图像作为示例(HOG (Histogram of Oriented Gradients) image feature extraction, image as an example to lena)

fcm聚类分析,用距离方法进行聚类画图，有一定的可操作性(FCM clustering analysis, using distance method for clustering drawing, has a certain operability.)

说明：  K-均值聚类算法，对数据进行聚类分析，可用于提取关键帧等。用matlab实现(K-means clustering algorithm, cluster analysis of data that can be used, such as key frame extraction. Using matlab to achieve)

稀疏自适应匹配追踪算法，无需稀疏度，就可以重构原始信号。(Sparse adaptive matching pursuit algorithm, without sparsity, we can reconstruct the original signal.)

区域图象分割的源码，基于区域增长的分割的代码(Image segmentation of the source region, regional growth based on code division)

matlab code for processing of signals and images

该资料中的程序实现的是图像压缩，供初学者学习。(The data of the program implementation is the image compression, for beginners to learn.)

用matalab编译的，求取 车牌图像的方法，很实用下载后 导入目标图像即可(The compiler with matalab, and calculate the license plate image, the method of practical import target image after download )

对于读入的彩色图像在rgb和hsv域中进行均衡，并显示比较均衡效果(To read the color image in rgb and hsv domain balanced and shows the effect of a more balanced)
