t’s a relatively easy thing for computers to “see” video, but “computer vision” goes a step further, applying a wide range of techniques by which computers can begin to understand and process the content of a video input. These techniques tend toward

驱动摄像头且获取一视频，并对视频中单车道上的车辆进行统计。-Driver camera and gets a video, and video of the single lane on which the vehicle statistics

The program connects and begins to grip the camera with cvCreateCameraCapture (), then get the width and height frame with cvGetCaptureProperty (). And then in the loop with cvQueryFrame () gets the image from the camera and displays the window.

采用在线学习跟踪方式，对物体进行跟踪，代码用c++编写，库用的Opencv库，程序中包括了3个.h，3个.cpp，一个.main程序。-We have added two new state-of-the-art object tracking algorithms to OpenCV which can robustly track images patches across a video sequence and learn online (i.e., on-the-fly) as the
