VIDEO INDEXING BASED ON VIEWERS' BEHAVIOR AND EMOTION FEEDBACK

A method and a corresponding apparatus for video indexing based on viewers' behavior and emotion feedback automatically index a multimedia sequence using viewers' casual feedback while watching the multimedia sequence. The method and apparatus use a system, such as an emotion detection system that includes one or more multimedia acquisition devices, such as video cameras, to detect viewers' behavior and emotion feedback, and to produce as video indices various categories of behavior and emotion segments. Each video camera may include one or more image sensors and/or audio sensors. The viewers or other users, i.e., user, may later selectively view the multimedia sequence by browsing through the video indices of various categories of emotion. The video indices are similar to chapters within digital video disc (DVD) movies that enable a user to jump directly to a particular chapter without having to fast forward.
