实现高通和低通滤波，主要是先进行傅里叶变换，然后对频谱图滤波后再逆变换得到滤波之后的图片(High-pass and low pass filter, mainly the first Fourier transform, frequency spectrum and then inverse transform filter and filtered image)

稀疏分解图像重建程序，把图像分解成多个小块图像，然后再各个子块重建后边缘处理后合并成整个图像。(sparse decomposition image reconstruction process, the image is divided into a number of small images, then each sub-block redevelopment edge after the merger into the whole image.)

说明：  老外的电机学教材，最为重要的是有相应的MAtlab代码，每一章都有，十分详细，学习电机的必备工具书，文件是在太大，此处上传chap2的源码(Foreigners motor learning materials, the most important thing is there is a corresponding MAtlab code, each chapter has a very detailed study of the motor necessary books, documents are too large to upload here chap2 source)

图像合成 内容：随意选择两个图像，选择其中一张图像中的部分内容，利用 matlab 编程添加到另一张图像中；所有的代码添加了注释(the choice of two images, choose one of parts of the image, by using matlab Programming is added to another in the image All of the code to add comments )

It calculates the Power Delay Profile of a multipath environment. A detailed procedure is given

二相编码信号的产生以及频谱分析，可以产生7位、11位、13位典型编码信号以及13位bark码的频谱图，通过仿真可用(Two-phase coded signal generation and spectrum analysis, can produce 7, 11 and 13 typically coded signals and 13 yards of bark frequency spectrum, through the simulation can be used)

边缘检测低通高通滤波本人已经试过绝对有用(Edge detection of high-pass filter low-pass, I' ve tried absolutely useful)

改进的粒子群算法--自适应粒子群算法，在普通的粒子群算法里面加入了熵和平均粒距的概念，收敛速度大大提高，而且不容易陷入局部最优，能更有效的解决复杂问题。(improved PSO-- Adaptive PSO. In a normal PSO which joined the entropy and the average particle from the concept of convergence speed, it is not easy to find the global optimum, the more effective solutions to complex problems.)
