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.
It's unclear whether this achieves the level of tech on the old "24" TV show, where Jack Bauer could identify people on surveillance footage in a matter of seconds, but it's still an interesting scenario for large-scale security setups.
