SurveillanceIncreasingly, surveillance technology is fielded to help safeguard public spaces such as train stations, shopping malls, street corners, in view of mounting concerns about public safety. Traditional surveillance systems have a human operator in a control room monitor a wall of CCTV screens for specific events that occur rarely. This is not only cost-inefficient but also error-prone, as the number of cameras increase. Advanced surveillance systems "enrich" the collection process by automatically filtering-out spurious information and presenting the operator only those parts of data which are likely to be security-relevant.CASSANDRA Project: Aggression Detection by Fusion Video and AudioExisting surveillance systems have limited capabilities; they typically perform video-based intrusion detection, and possibly object tracking, in fairly static environments. The CASSANDRA project (Context-Aware SenSing for AggressioN Detection and Risk Assessment, 2005-2009) involves the more ambitious goal of human activity recognition in dynamic environments, in particular, automatic aggression detection. Because events associated with the build-up or enactment of aggression are difficult to detect by a single sensor modality (e.g. shouting versus hitting-someone), CASSANDRA will combine audio- and video-sensing. to form high-level, cognitive descriptions of scene activity, incorporating prior-knowledge about application context.
