I had ran a coding for background subtraction from the video for offline. I used openCV 2.4.9 and Visual Studio 2013 to run the coding. The video can display and play but the problem is the coding for background subtraction does not functioning. Can anybody help me what is the wrong for my coding? Someone had tell me the error is
if (strcmp(argv[1], "-vid") == 0)
{
//input data coming from a video
processVideo(argv[2]);
}
so, what i need to do?
