A number of algorithms have been recently proposed for automatic intruder detection from CCTV images.Past researchers have typically tested these algorithms on centralized networks where all images are transmitted to a central control room.This paper demonstrates the applicability of a selection of such algorithms to a distributed network of wireless sensors.A distributed network of wireless visual sensors was simulated using a number of high-resolution webcams setup in the hallways of an academic building.The selected algorithms were then applied in a distributed fashion at each node.An empirical comparison of the most popular of the recent algorithms on a simulation of a wireless sensor network was thus obtained.This paper provides corroborating evidence in support of the most effective of such algorithms to the problem of automatic anomaly detection from image streams.
