I'm a new user of matlab. I searched so many resources to extract frames from a football video and each time I tried there are lots of errors. All I need is to take a video as input and divide it into frames. From each frame I need to find the position(Coordinate X & Y) of the football.
Please anyone help me.

Start your own thread and post your image(s) there. And explain better that "shows me circles only on plot not in video transmission" means.
