DARBY, J., LI, B. and COSTEN, C., 2008. Human activity tracking from moving camera stereo data. BMVC 2008 - Proceedings of the British Machine Vision Conference 2008, 1st-4th September, University of Leeds, Leeds, UK, pp.86.1-86.10
We present a method for tracking human activity using observations from a moving narrow-baseline stereo camera. Range data are computed from the disparity between stereo image pairs. We propose a novel technique for calculating weighting scores from range data given body configuration hypotheses. We use a modified Annealed Particle Filter to recover the optimal tracking candidate from a low dimensional latent space computed from motion capture data and constrained by an activity model. We evaluate the method on synthetic data and on a walking sequence recorded using a moving hand-held stereo camera.
