Abstract
An apparatus for monitoring movement of objects of interest in an area includes an activity map generation circuit and a unified activity map generation circuit. The activity map generation circuit is configured to: generate a plurality of activity maps based on video content from a plurality of cameras, each of the plurality of activity maps being indicative of relative activity of the objects of interest over time within a field of view of a camera among the plurality of cameras, and each of the plurality of cameras having a different corresponding field of view in the area; and standardize the plurality of activity maps with regard to a single common point of view. The unified spatial activity map generation circuit is configured to combine the plurality of standardized activity maps into a unified activity map.
