Real-time pattern recognition and contour tracing with opencv

Hi everyone!

I have a project to detect a pattern on an object and trace his contour in real time. I'm new user of Opencv, and I don't really know how to start!

I've tried some tutorials, for example "matching with surf + homography", "hough lines" and "hough circles"... I've realized that there were many methods that could be used to detect a pattern, but they don't necessarily work in real time because they are too slow.

The pattern I want to detect could be a circle, but in other application a rectangle or an elipse, and eventually a nondescript pattern. Hough circle works well in real time and traces the contour as I want, but it only works with a circle so I can't chose the pattern I want to detect, that's why I need your help.

What is according to you the best method to realize my project? I don't want a script, just ideas to help me, because I'm a little lost!

Thanks a lot!
