In the end, DeAngelo installed a web camera with a bird's eye view of 5th Avenue and wrote code that could track the real-time positions of the cars, but he also found a way to segment the foreground so the computer could tell the difference between stationary objects in the picture (ex: street, buildings) from the moving objects (cars). By transmitting the car information into pixel data and live streaming it in real-time, the positions of the cars could be mapped into car graphics in the virtual arcade game, driving down the road in real-time."
