Ness Technologies' Sixth Sense is a system that identifies suspicious persons in an urban scene. It automatically alerts the end user to abnormal patterns of motion. A scene is surveilled by video cameras. All moving objects (e.g., humans, animals, vehicles) are automatically detected and tracked. Each trajectory is carefully examined in order to determine whether it is normal or not. Two types of alerts are produced by the system. The first is based on user definitions, such as loitering, running, abrupt direction changes, etc. The second is based on system self-learning. It accumulates statistics during the learning stage and applies them to each incoming trajectory during the recognition stage. The Sixth Sense can also be integrated within the ASM (Area Smart Monitoring) as a source of information immediately and directly contributing to the urban situation picture generated by the ASM. Sixth Sense successfully deals with crowded urban areas where human operators can hardly perceive and absorb all the incoming information. In such situations the system draws the operator's attention to specific events in the scene.
