A new camera system for San Francisco's MUNI system will use algorithms and machine learning to track and monitor commuters. San Francisco's Municipal Transit Authority, which oversees the city's MUNI trains, has signed a contract with security firm BRS Labs to deploy cameras to 12 subway stations that use algorithms and machine learning techniques to spot anomalous behavior. BRS Labs is a security firm that provides behavior recognition software for video surveillance. Servers connected to security cameras observe locations for weeks at a time and then establish a baseline of normal behavior based on this timespan; Apart from machine learning-based video surveillance, subway security has also taken on wackier (and scarier) aspects: The Homeland Security Department has publicly announced their plans to release bacteria into Boston T tunnels this summer in order to test new biological weapon detectors deployed throughout the subway system......
