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 fr a me 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.)
