Int. Workshop on Image Analysis for Multimedia Interactive Services (WIAMIS,',','), invited paper, Montreux, Apr. 2005.}, abstract = {Automatic meeting analysis is an emerging research field. In this paper, we present stochastic algorithms for tracking people in multi-sensor meeting rooms, for a number of relevant tasks, including tracking multiple people, tracking head pose towards analysis of visual focus-of-attention, and tracking speaker activity using audio-visual information. A Bayesian framework based on Sequential Monte Carlo methods is used in all cases. We discuss the advantages and limitations of our approach, illustrate it with results, and highlight a number of open issues.}, pdf = {https://publications.idiap.ch/attachments/reports/2004/rr-04-71.pdf}, postscript = {ftp://ftp.idiap.ch/pub/reports/2004/rr-04-71.ps.gz}, ipdmembership={speech, vision}, language={English}, }
