Japanese surveillance system scans 36 million faces in seconds

IT World: Interesting stuff out of Japan - DigInfo has a video showing a new system created by Hitachi Kokusai Electric that can scan more than 36 million faces based on surveillance footage or regular photos in about a second. The high speed is "achieved by detecting faces through image recognition when the footage from the camera is recorded, and also by grouping similar faces," a spokesman says.

The story is too old to be commented.
