Hi! I'm 19 years old, I'm learning Information Technology , now I'm in a research for student, my topic is confirm object in a video ( object is only car and man ) Video is taken form fixed camera and I must confirm in video what is man, and what is car. Our idea is use a background, and then split video into a frame, after that, subtract each frame with the background, we will find the object and confirm it. I will use matlab for this instead of open cv but I never have use matlab before :( Can you help me?

Here is an example of how to detect and track moving objects with a stationary camera. Deciding whether an object is a car or a person is another matter. Since people are generally vertical and cars are horizontal, the aspect ratio may actually get you results decent enough for a school project.

If you want to do something more sophisticated, the Computer Vision System Toolbox also comes with a vision.PeopleDetector object. If you want to go further, you can try training a car detector with the trainCascadeObjectDetector function.
