matlab实现三维重建

利用Orb算法实现图像特征点的提取，并且通过前后两帧之间的特征点进行特征匹配，为视频稳像、图像融合以及图像识别提供前提条件。(Detecting feature points using Orb algorithm, then matching the points with the detected points frames.That method provide one new way to video stablization ,image fusion and image recognition etc. )

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.)

这是我们非线性课程的一次作业，有分岔图，蛛网图，庞加莱截面，希望对大家有用。(This is our first non-linear operation of the curriculum, there is bifurcation diagram, spider diagram, Poincare section, in the hope that useful to everyone.)

说明：  二维功率谱密度计算程序 使用傅里叶变换，可以计算功率谱密度(Two dimensional power spectral density calculation program using Fourier transform)

说明：  适用于任意图像中轮廓的直线段检测与描绘，对于公路车道直线检测具有良好效果。(Linear segment detection and description for contours in arbitrary Images,it has good effect for straight line detection of highway lanes.)

不错的SVM实现算法,采用的是LS-SVM算法,这是C版本,还有一个MATLAB版本(A good SVM implementation algorithm, using the LS-SVM algorithm, this is the C version, there is a MATLAB version)

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)

说明：  使用PSTD计算方法实现的3维时间反转镜像技术算法，可用于声学及电磁学成像(A Time Reversal Mirror Algrithm devopled by the 3 dimensial PSTD numerical method, it can be used in acousic and electromagnitic imaging field)

说明：  SAR图像非局部平均滤波，包括高斯平滑，PSNR检测(SAR image non local average filtering, including Gaussian smoothing, PSNR detection)

用VB写的画出波纹的程序(Written by VB painted corrugated procedures)
