orthogonal Matching Pursuit(OMP),CoSaMP算法的Matlab实现。(orthogonal Matching Pursuit(OMP),CoSaMP Algorithms)

用大整数乘法来计算两个n位二进制数相乘(With large integer multiplication to calculate the multiplication of two n-bit binary number)

这是基于图论的图像分割源代码，效果很好，欢迎下载.(This is based on graph theory image segmentation source code, works well, welcome to download.)

背景减除的完整算法，《A Statistical Approach for Real-time Robust Background Subtraction and Shadow Detection》作者源代码(The "src" folder contains all of the source code. To run the program, follow these simple steps: 1. Start MATLAB and ensure the "src" folder is your current working directory. 2. Edit "bs.m" and "classify.m" so that the file paths point to the proper directories as specified. 3. In the MATLAB environment type "bs" which will train the background model from the sequence you specified in (2). 4. In the MATLAB environment type "classify" which will classify the sequence of images you specified in (2). 5. Now the classified images should be saved to disk in the folder you specified in (2).)

用C编写程序来求解圆的面积和周长，这是以前的一个实习作业。(Write a program in C to solve the area and perimeter of a circle, which was previously an internship job.)

使用sift+RANSAC完成两幅图像的特征提取和匹配，并将较小图像区域在另一幅中用方框圈出来。运行plot.m。(This code uses sift and RANSAC to extract features of two images and then finds and marks the smaller image in the other image.run plot.m)

说明：  机载合成孔径雷达自聚焦算法，没有实测数据，用的是点目标仿真(Airborne synthetic aperture radar algorithm for self-focusing, there is no measured data, using a point-target simulation)

采用了光流法实现了目标跟踪与分割，用于高精度仿真与模拟(Optical flow method to achieve the target tracking and segmentation for high-precision simulation and modeling)

说明：  次文件夹包含两个程序，可以对振动信号进行包络分析，适合信号处理入门的朋友(do envelope analysis on vibration signal)
