In this paper, we present a system that combines sound and vision to track multiple people. In a cluttered or noisy scene, multi-person tracking estimates have a distinctly non-Gaussian distribution. We apply a particle filter with audio and video state components, and derive observation likelihood methods based on both audio and video measurements. Our state includes the number of people present, their positions, and whether each person is talking. We show experiments in an environment with… CONTINUE READING
