Question

I have a task that is detect some people or something who enter into the sight of web camera, and then my system will be alarm.

Next step is recognize which kind of thing the object is, in this phase I know use Hough transform to detect line, circle, even rectangle. But when a people come into the sight of camera, people’s profile is more complex than line, circle and rectangle. How can i recognize the object is people not a car.

I need help to know that.
