A Bayesian Framework for Robust Reasoning from Sensor Networks

Valery A. Petrushin, Rayid Ghani, and Anatole V. Gershman

The work described in this paper defines a Bayesian framework to use noisy, but redundant data from multiple sensor streams and incorporate it with the contextual and domain knowledge that is provided by both the physical constraints imposed by the local environment where the sensors are located and by the people that are involved in the surveillance tasks. The paper also presents the preliminary results of applying the Bayesian framework to the people localization problem in indoor environment using a sensor network that consists of video cameras, infrared tag readers and a fingerprint reader.
