Audiovisual Information Fusion in Human–Computer Interfaces and Intelligent Environments: A Survey

Shankar T. Shivappa, Mohan Manubhai Trivedi, Bhaskar D. Rao
2010 Proceedings of the IEEE  
Intelligent systems with audio-visual sensors should be capable of achieving similar goals. The audio-visual information fusion strategy is a key component in designing such systems.  ...  The fusion strategy used tends to depend mainly on the model, probabilistic or otherwise, used in the particular task to process sensory information to obtain higher level semantic information.  ...  We also like to acknowledge the assistance provided by our colleagues for reviewing the manuscript and providing valuable suggestions to improve the presentation of the paper.  ...
