Hebrew University of Jerusalem computer scientist Shmuel Peleg has developed video synopsis software that compresses hours of video into just minutes, enabling police to quickly review action captured on surveillance cameras.
Although law enforcement agencies increasingly are relying on surveillance video to solve crimes, the amount of video can be overwhelming. Peleg's software addresses this problem by combining actions that occur at different times.
"At the first stage, we separate automatically the moving object[s] from the static background," he says, such as people entering and exiting a building. The software then replays the scene as if the people moved through the area simultaneously. "We pack as many objects as we can from as many different times as we can, so that we can see all the object(s) and all the activities in as short as possible (a) time," Peleg says.
The technology offers an enormous benefit for investigators because it can reveal patterns in behavior, says former Israeli military intelligence officer Mordechai Kedar.
