Abstract:
A method for managing image information in a monitoring system having at least one monitoring module for monitoring a monitored location and a remote recipient unit, said method comprising the steps of:recording an image of the monitored location using the monitoring module; in response to a change occurring during image recording as relating to at least one object in said image, segmenting said object to create a distinct region by comparison of the recorded image with a reference image in the monitoring module including by generating, from the recorded image and a reference image of the monitored location, a difference image containing at least a portion of the object; in response to said segmenting, creating an outline shape in the monitoring module by tracing along edge of the distinct region, said outline shape being a representation of the edge of the distinct region; transmitting data representing the outline shape to the recipient unit, said outline shape reducing transmission time and bandwidth from transmitting said segmented object represented by the distinct region, or maintaining privacy of the object by not allowing detailed recognition including where the object has a human shape; recreating the outline shape in the recipient unit using said transmitted data; and displaying the outline shape visually in the recipient unit.
