Suggested starting point in real time image processing

Hi,

I am new to image processing/segmentation and I have a project where a digital camera will be attached to a robot which will enable to the robot to follow a red bouncing ball.

I am not sure where I should start from as the image needs to be processed using matlab in real-time.

From the reading I have done I think I need to start with finding the ball possibly by comparing 2 frames and seeing what has changed between them.

So any suggestions such as I am heading on the right path or I should look into doing it XXXX way would be greatly appreciated.

That's fine. Give it a shot. I've seen MATLAB be pretty responsive (i.e. quick) to tracking objects at video rates even when you have to do image processing on each frame.

I hope you have a the image acquisition toolbox. Make sure you use callback functions that are triggered every few frames, and not "getsnapshot", which I find to be very slow.
