绘制矢量水听器的心形指向性，方便初学者使用(Drawing the heart directivity of a vector hydrophone,this thing is convenient for beginners to use)

图像几何变换（缩放、旋转）中的插值算法 ( The picture geometry transformation (缂╂斁, revolves) the center interpolation algorithm )

说明：  机载正侧视SAR雷达仿真和成像，使用matlab编写，直接运行可用(Simulation and imaging of airborne forward-looking SAR radar)

NASA开源的匹配追踪分解算法，用于信号分解以及特征提取。(Matching Pursuit Decomposition is a powerful and effective iterative algorithm for signal decomposition and feature extraction. Matching Pursuit Decomposition decomposes any signal into linear combinations of its dictionary elements or atoms.)

只能信息树立的相关课件和Matlab源代码，对于学习只能信息处理的学员很有帮助。(Information can only be set by the relevant courseware and Matlab source code, for students to study information processing can only be helpful.)

经典迭代直方图分离聚类算法，该聚类算法基于图像直方图，非常适合于多类目标分割，计算速度非常快(Classical iterative separation histogram clustering algorithm, the clustering algorithm based on image histogram, very suitable for many types of object segmentation, calculation of very fast)

08年新的Delaunay程序，很不错的！(Delaunay new 2008 program, it is good!)

1.首先从文件菜单打开程序目录下的car.avi视频,系统将显示视频的第一帧。 2.点击背景提取菜单，稍后会提取出背景并显示在打开的第二个窗口中。 3.当提取出背景后，点击检测跟踪菜单，对车辆进行检测和跟踪。 4.点击轨迹绘制菜单，绘制车辆的轨迹。 注：由于使用OpenCV打开AVI视频文件需要视频解码器，故在程序运行前请在电脑上先安装DivX类型的的视频解码器，否则将出现无法打开文件的错误。本程序使用的是OpenCV2.1版本，在没有安装此版本软件的机器上运行时需要将cv210.dll,cvaux210.dll,cvcore210.dll,highgui210.dll,ml210.dll这五个文件拷贝至*.exe可执行文件下。(First, open the CR. AVI video from the file menu and the system will display the first frame of the video. 2. Click on the Background extract menu and the background will be extracted later and displayed in the open second window. 3. When the background is extracted, click on the Test Tracking menu to test and track the vehicle. 4. Click on the trajectory drawing menu to map the trajectory of the vehicle. Note: Since a video decoder is required to open an AVI video file using OpenCV, install a DivX-type video decoder on the computer before the program runs, otherwise an error will occur that can not open the file. The program uses OpenCV2 .1, which requires five files to be copied to *, cv210. DLL, cvaux 210. DLL, cvcore 210. DLL, highgui 210. DLL, ML 210. DLL. Exe under executable.)

说明：  tv全变差去噪。自己编写的自适应去噪，传统去噪。保真去噪(TV total variation de-noising. Self-adaptive denoising, traditional denoising. Fidelity de-noising)

自己编写的C++小程序，十字算法，用到KD树，能够有效进行点云去噪，压缩数据(I have written a small program C++, cross algorithm used in KD tree, the point cloud can be effectively de-noising, compression of data)
