Ok so the fact that he has produced this himself, using off-the-shelf commodity laptops etc is really great. But this technology doesn't seem new to me - technology already exists for surveillance cameras in police and military helicopters to track an object like a car and keep it in vision as the helicopter turns and maneuvers. Likewise, facial recognition - both statically and within a video stream - isn't new either. Not taking anything away from the guy, but just wondering what it is I'm not getting that is new/amazing with this particular implementation?
