A probabilistic graph-based framework for plug-and-play multi-cue visual tracking.

In this paper, we propose a novel approach for integrating multiple tracking cues within a unified probabilistic graph-based Markov random fields (MRFs) representation. We show how to integrate temporal and spatial cues encoded by unary and pairwise probabilistic potentials. As the inference of such high-order MRF models is known to be NP-hard, we propose an efficient spectral relaxation-based inference scheme.
