Abstract: Output from a video camera is monitored. Input data is analyzed to produce a model of a background image and incoming image data is compared with said background model to identify images having a high level of activity created by the introduction of a foreground object. A period of activity, composed of a plurality of consecutive images having a high level of activity, is identified, and an exemplar image is generated.

Abstract: An object monitoring system, including a slave system having slave processors (14, 16) and a plurality of cameras (10) for monitoring one or more objects, images of the cameras (10) being processed by respective ones of the slave processor (14, 16), and the slave processors including sensors (30) assigned to respective cameras (10) and at least parts of the fields of view of the cameras (10) to detect predetermined characteristics of the at least parts and generate a trigger in response thereto. A master system has to master processor (20) including agents (34) assigned to at least one of the objects and having one or more of the sensors (30) allocated thereto, the agents (34) each generating an event on receiving triggers from the one or more allocated sensors (30). An event system (6) receives the events and determines whether an alarm condition exists. A user interface system (8) can configure the sensors (30) and agents (34) and respond to events.

Abstract: An environment is monitored by capturing image data depicting the environment and analysing the image data to identify moving foreground objects. Upon identifying an object, the movement of said object is tracked, and graphical output data is generated providing a representation of the movement superimposed upon a representation of said environment.
