IBM, Microsoft, and academic researchers are trying to invent ways to find specific images in video footage. ¶ For 20 years, computer scientists have been working on improving ways to search among reams of video clips for a particular shot. New research by IBM, Microsoft, and academic teams studying the problem could bring them a step closer to that goal. ¶ At a conference in Cambridge, England, last week, an IBM researcher gave the first public demonstration of a computer system called Marvel that uses statistical techniques to learn about relationships between colors, shapes, patterns, sounds, and other clues from video footage that can help identify its content. IBM's prototype then labels the footage so users can go back and find individual shots. That could be a boon not only to TV news producers but intelligence analysts watching surveillance video and even PC users editing home movies. ... Link: InformationWeek 8/30/04.
