    We explore the loss behavior encountered in transmitting real-time voice over the Internet and propose a new loss-concealment scheme to improve its received quality. One known technique to conceal loss is to send interleaved streams of voice samples and reconstruct missing or late samples by interpolation at the receiver. Based on this method, we propose a new transformation-based reconstruction a... View full abstract»

    We present a statistical approach to developing multimodal recognition systems and, in particular, to integrating the posterior probabilities of parallel input signals involved in the multimodal system. We first identify the primary factors that influence multimodal recognition performance by evaluating the multimodal recognition probabilities. We then develop two techniques, an estimate approach ... View full abstract»

    Efficient indexing methods are required to handle the rapidly increasing amount of visual information within video databases. Video analysis that partitions the video into clips or extracts interesting frames is an important preprocessing step for video indexing. We develop a novel method for video analysis using the macroblock (MB) type information of MPEG compressed video bitstreams. This method... View full abstract»

  • Issues of quality and multiplexing when smoothing rate adaptive video

    We have proposed a smoothing and rate adaptation algorithm-SAVE (Smoothed Adaptive Video over Explicit rate networks)-for transport of compressed video over rate-controlled networks. SAVE attempts to preserve quality as much as possible, and exercises control over the source rate only when essential to prevent unacceptable delay. In order to understand the impact on quality of rate adaptation, we ... View full abstract»
