International Conference on Neural Information Processing
作者: N. Sriraam R. Kannan C. Eswaran Faculty of information Technology Multimedia University Cyberjaya Malaysia
Lossless compression of electroencephalograph (EEG) data is of great interest to the biomedical research community. Lossless compression through neural network is achieved by using the net as a predictor and coding th... 详细信息

IEEE Symposium on Computers and Communications (ISCC)
作者: Y. Hinard H. Bettahar Y. Challal A. Bouabdallah Heudiasyc Laboratory University of Technology of Compiegne France
Security and QoS are two main issues for a successful wide deployment of multicast services. For instance, in a multicast streaming application, a receiver would require a data origin authentication service as well as... 详细信息

International Conference on Digital Signal Processing (DSP)
作者: G. Sinevriotis T. Stouraitis Department of Electrical and Computer Engineering University of Patras Patras Greece
A computationally efficient block matching algorithm is presented to perform motion estimation of image sequences. The algorithm evaluates an objective function for all neighbouring blocks and stops, when no further i... 详细信息

International Conference on Acoustics, Speech, and Signal Processing (ICASSP)
作者: J. Thyssen H. Nielsen S.D. Hansen Tele Denmark Research Horsholm Denmark Electronics Institute Technical University of Denmark Lyngby Denmark
Addresses the question of how to extract the nonlinearities in speech with the prime purpose of facilitating coding of the residual signal in residual excited coders. The short-term prediction of speech in speech code... 详细信息

IEEE Workshop on Multimedia Signal Processing
作者: Xiaohan Wang Xiaolin Wu Department of Electrical and Computer Engineering McMaster University Hamilton ONT Canada
Linear predictors for lossless data compression should ideally minimize the entropy of prediction errors. But in current practice predictors of least-square type are used instead. In this paper, we formulate and solve... 详细信息

IEEE International Symposium on Information Theory
作者: Jing Hu Jerry D. Gibson Department of Electrical and Computer Engineering University of California Santa Barbara CA USA
We revisit the classic problem of developing a spatial correlation model for natural images and videos by proposing a conditional correlation model for relatively nearby pixels that is dependent upon five parameters. ... 详细信息

IEEE International Conference on Image Processing
作者: K.H. Yang A.F. Faryar Bell Laboratories Lucent Technologies Inc. Holmdel NJ USA
We propose a new approach to context-based predictive coding of video, where the interframe or intraframe coding mode is adaptively selected on a pixel basis. We perform the coding mode selection using only the previo... 详细信息

IEEE International Symposium on Circuits and Systems
作者: Hsuan-Tsung Wang Walter D. Leon-Salas Computer Science Electrical Eng. Dept. University of Missouri-Kansas City Kansas City MO USA
An image compression algorithm suitable for focal plane integration and its hardware implementation are presented. In this approach an image is progressively decomposed into images of lower resolution. The low resolut... 详细信息
