The problem of tracking multiple moving speakers in indoor environments has received much attention. Earlier techniques were based purely on a single modality, e.g., vision. Recently, the fusion of multi-modal information has been shown to be instrumental in improving tracking performance, as well as robustness in the case of challenging situations like occlusions (by the limited field of view of...
Speaker tracking in smart environments has attracted an increasing amount of attention in the past few years. Our recent studies show that fusing audio and visual modalities can provide improved robustness and accuracy in some challenging tracking scenarios such as occlusions (by the limited field of view of cameras or by other speakers), as compared with the tracking system based on individual modalities...
