说明：  利用微粒群算法（pso）优化支持向量机（SVM）的参数-c,-g(Using pso optimized support vector machine parameters-c,-g)

实现半脆弱小波提取，实现文献A FEATURE-BASED SEMI-FRAGILE WATERMARKING SCHEME IN DWT DOMAIN.pdf的源码(Achieve semi-fragile wavelet extraction, to achieve literature A FEATURE-BASED SEMI-FRAGILE WATERMARKING SCHEME IN DWT DOMAIN.pdf source)

定义坐标轴的显示范围用axis指令 语法：axis([xmin xmax ymin ymax]) 你的例子ymin ymax应分别设为0和0.5，xmin xmax 取周期的两端。 然后再plot（x,y） 欢迎一起探讨matlab的使用：） (draw picture in matlab)

说明：  LDPC的编码和译码程序 采用vc及matlab(LDPC coding and decoding process, and matlab using vc)

基于VC++和Matlab实现的常用图像编码算法，包括Huffman编码、Fano编码、算术编码、游程编码、Shannon编码及信源熵的计算的常用编码算法。(VC++ and Matlab common image coding algorithms, including Huffman coding, Fano coding, arithmetic coding, run-length coding, Shannon coding and source entropy calculation commonly used coding algorithm.)

this is an MDL method for system order estimation

alpha-beta滤波器是一种很实用的滤波器，可以和卡尔曼滤波，信息滤波器做比较，对于初学者有很大帮助(alpha-beta filter is a very practical filter can Kalman filter, the information filter comparison, are very helpful for beginners)

water marking of an image.you can use the code.please try to run the code

谱聚类的matlab实现，其中包括k-means的实现，谱聚类聚类结果要优于k-means的聚类结果(Spectral clustering matlab code, including the code of k-means, spectral clustering results is better than k-means clustering results)
