Violent Scenes Detection – automatically detects violent scenes in movies
All content providers may be interested in the violent scenes detection technology to manage efficiently their content database. In particular, the violent scenes detection technology is an interesting feature for VOD services, as it may help users select a movie suitable for the entire family.
The Violent Scenes Detection module is a system which detects automatically the most violent scenes in a movie. Provided with a set of pre-computed audio and video features from a video stream, the system will output a file with the corresponding violent scenes timecodes. The chosen pre-computed features were proved to be discriminative for the task of violent scenes detection. They are used as an input for a classification sub-system based on Bayesian networks. This sub-system was trained and its parameters learned offline, on a movie database.
The Bayesian model structure was also automatically learned, without using any expert knowledge. The structure learning property enables one to automatically train another model on another type of videos to detect some other type of events, without building the structure of the model manually.
