AI Guardsman uses computer vision to spot shoplifters

Have a nagging feeling that someone -- or something -- is watching you? Chances are it's a camera. Cities around the world employ computer vision-enabled CCTV to monitor vehicle and pedestrian traffic. And in the near future, brick-and-mortar stores might use them to nab shoplifters. Japanese telecom company NTT East teamed up with tech startup Earth Eyes to create AI Guardsman, a machine learning system that attempts to catch crooks in the act.
