Smile – new video recognition software scans 36 million faces per second

Upcoming Hitachi system stores recorded faces as indexed biometric records for faster retrieval.

Currently, the system needs at least a 40 x 40 pixel image of a face to function, and the field of view is fairly narrow at 30 degrees. Hitachi Kokusai Electric explains the system in this video. Aimed at large scale surveillance users, like railway stations and department stores, the primary audience for a system of this type will likely be law enforcement agencies.

Searches can be started with a tagged video image, or a still photo from a camera or even a Facebook profile. Facial types are indexed and stored together for faster retrieval. Results appear as a series of thumbnails. Clicking on any thumbnail runs video before and after the indexed face appears. No pricing details have been released.


A system identifying 36 million faces per second could do the entire planet in just over 3 minutes.

Possible uses

Coupling this info with DNA samplings and good old fashioned fingerprinting from every human and the "America's Most Wanted" list may shrink a bit faster.

Bad news for shoplifters and criminals.

When I worked in a casino they had a type of system like this (obviously on a lower scale). Worked very well, the door would not open until it got full facial recognition (which means no hats, etc).

Privacy? Less and less. 36M now, how fast in 2020? By that time, a system's abilities will be down to seconds. Amazing. Frightening.

Anybody still think CCTV is harmless?

People willing to trade their freedoms for some temporary security; deserve neither, and will lose both.

Any chance Homeland Security and the TSA aren't the first customers? If so, will a mistyped name in the facial recognition database mean you can never fly again?
