1. A method for estimating the activity topology of a set of sensed data windows in a networked system of sensors, each of the sensed data windows related to a corresponding sensed region associated with a given sensor, the method including the steps:
- determining a subset of sensed data windows having corresponding sensed regions that are not connected by comparing sensed data windows pair wise from the set of sensed data windows; and
excluding the subset of sensed data windows that are not connected from the set of sensed data windows thereby eliminating these pairs of sensed data windows from the networked system of sensors and determining the active topology.

Abstract
A method for estimating the activity topology of a set of sensed data windows is described. Each of the sensed data windows related to a corresponding sensed region. The method includes the steps of determining a subset of sensed data windows that are not connected; and excluding the subset of sensed data windows from the set of sensed data windows. In one embodiment, the sensed data windows corresponding to image windows such as would be provided by a visual surveillance system.

11. A network surveillance system including:
-
a network of sensors, each sensor providing one or more sensed data windows each corresponding to a sensed region and forming in total a set of sensed data windows; and data processing means to determine a subset of sensed data windows having corresponding sensed regions that are not connected by comparing sensed data windows pair wise from the set of sensed data windows and exclude the subset of sensed data windows that are not connected from the set of sensed data windows thereby eliminating these pairs of sensed data windows from the network surveillance system and determining an active topology of a set of sensed data windows. - View Dependent Claims (19, 20)
