Computers Sort Video Files to Find Criminals

In an attempt to capitalize on the ubiquity of security cameras, police are trying to search thousands of videos for suspected criminals. They input specific criteria — the name of a weapon or a region — and the computer determines if any of the images are a match.

But there is too much video to sort through. With new equipment, police in Cincinnati and in a handful of other cities will be able to archive and find videos based on certain specifications, as in: all female bank robbers using shotguns; convenience store hold-ups where the suspect wears a blue baseball cap; and other cross-referenced criteria.

Ann Thompson reports from member station WVXU in Cincinnati.
