利用OpenCV对视频进行处理，尝试打开本电脑上的摄像头作为视频输入设备，或者将命令行的输入参数作为文件名来打开的视频文件。不管是哪一种方法，最后都是不断的循环处理一帧一帧地处理，涉及到的图像处理有背景擦除，平滑滤波，二值化等。-Using OpenCV to process the video, try to open the computer input device as a video camera, or the command line input parameters as the file name to open the video file. Whatever the method, the last cycle of treatment are continuously frame by frame to process, involving a background erase the image processing, filtering, binarization and so on.
