Reverberant environments pose a challenge to speech acquisition from distant microphones. Approaches using microphone arrays have met with limited success. Recent research using audio-visual sensors for tasks such as speaker localization has shown improvement over traditional audio-only approaches. Using computer vision techniques we can estimate the orientation of the speaker's head in addition to...
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...
