Tracking humans in an indoor environment is an essential part of surveillance systems. Vision based and microphone array based trackers have been extensively researched in the past. Audio-visual tracking frameworks have also been developed. In this paper we consider human tracking to be a specific instance of a more general problem of information fusion in multimodal systems. Dynamic Bayesian networks...
In this paper, we develop a robust wideband adaptive beamforming algorithm for microphone array based speech recognition. We develop a quadratic constraint based approach to deal with the uncertainty in the look direction. In order to address the ill-conditioning associated with the constraint matrix, diagonal loading (DL) is employed. The advantage of adding DL to the constraint matrix is that the...
