Software that powers facial recognition generally uses a two-step process, says David Alexander Forsyth, an artificial intelligence expert and chair of computer science at the University of Illinois at Urbana-Champaign. Step one is to figure out where the faces are in the image in question; the system is looking for a window-like section of the image that also has someone's countenance in it, and not the other stuff of modern life, like stop signs and cars.
A police officer wears a pair of smart glasses with facial recognition at Zhengzhou East Railway Station in China's central Henan province. It doesn't link a system of killer robots ticked off at the human race (just yet). But Chinese police are expanding the use of futuristic facial recognition tech powered by a system dubbed "Skynet" to track a database of blacklisted individuals. Unlike in the "Terminator" franchise where Skynet is controlled by machines to connect genocide-minded bots, this version is a tool for law enforcement and security that's being tested out for added security at two sessions of China's parliament this year, according to Reuters. The technology is the same we saw Chinese police use last month to monitor travelers leading up to Chinese New Year.
