SCOPES: Smart Cameras Object Position Estimation System

In this paper we present SCOPES, a distributed Smart Camera Object Position Estimation sensor network System that provides maps of distribution of people in indoors environments. Each node in the system is comprised of a cyclops camera that performs local detection and processing of the visual information and a tmote sensor node, which provides multihop communication. SCOPES uses local adaptive techniques that enables intelligent duty-cycling 1 between the active sensing and the information processing tasks performed at each node. The system switches between the fast and simple background subtraction algorithms for object detection, to the more computationally intensive object grouping algorithms for estimating the number and direction of travel of multiple persons in the local field of view. By aggregating meta-information generated by each node, SCOPES is able to minimize the total data transmitted in the network and still be able to generate an accurate density estimation map of t...
