- a) monitoring the roulette wheel of said roulette table with a video camera;
- b) processing each video frame obtained from the video camera so as to detect the presence of a ball on the roulette wheel;
- c) comparing the information obtained from each video frame to determine the relative speed of rotation of the ball around the roulette wheel;
- d) detecting when the speed of rotation has dropped below a predefined threshold signifying the end of a game;
- e) processing each video frame obtained from the video camera to detect movement within the betting area of the roulette table;
