Video telephony could be considerably enhanced by provision of a tracking system that allows freedom of movement to the speaker while maintaining a well-framed image, for transmission over limited bandwidth. Already commercial multi-microphone systems exist which track speaker direction in order to reject background noise. Stereo sound and vision are complementary modalities in that sound is good for initialisation (where vision is expensive) whereas vision is good for localisation (where sound is less precise). Using generative probabilistic models and particle filtering, we show that stereo sound and vision can indeed be fused effectively, to make a system more capable than with either modality on its own.
