International Conference on Telecommunications in Modern Satellite, Cable and Broadcasting Service (TELSIKS)
作者: S. Benk Department of Computer Science Ruhr University of Bochum Bochum Germany
One piece of information can often be expressed in different ways. Information is mostly stored directly, and can then also be interpreted directly. However, since each information can also always be assigned to a cer... 详细信息

IEEE International Conference on Image Processing
作者: S.D. Rane G. Sapiro M. Bertalmio Department of Electrical and Computer Engineering University of Minnesota Minneapolis MN USA
An approach for filling-in blocks of missing data in wireless image transmission is presented in this paper. When compression algorithms such as JPEG are used as part of the wireless transmission process, images are f... 详细信息

IEEE Workshop on Speech Synthesis
作者: A.B. Kain J.P.H. van Santen Center for Spoken Language Understanding OGI School of Science and Engineering Beaverton OR USA
A compression method is proposed that takes advantage of a powerful property of acoustic unit inventories: In the appropriate acoustic space, units that share a (context-dependent or -independent) phoneme label must b... 详细信息

IEEE International Conference on Acoustics, Speech and Signal Processing
作者: Aliaksei Sandryhaila Jelena Kovacevic Markus Puschel Electrical and Computer Engineering Carnegie Mellon University Pittsburgh PA USA Biomedical Engineering and Center for Bioimage Informatics Carnegie Mellon University Pittsburgh PA USA Computer Science ETH Zurich Zurich Switzerland
We propose an algorithm for the compression of ECG signals, in particular QRS complexes, based on the expansion of signals with compact support into a basis of discrete Hermite functions. These functions are obtained ... 详细信息
