Trellis-Searched Adaptive predictive coding of Speech
收藏 引用
IEEE TRANSACTIONS ON SPEECH AND AUDIO PROCESSING 1993年 第2期1卷 196-206页
作者: Malone, Kevin T. Fischer, Thomas R. Sandia Natl Labs Commun Syst Div Albuquerque NM 87185 USA Washington State Univ ECE Dept Pullman WA 99164 USA
This paper incorporates trellis coded vector quantization (TCVQ) and forward adaptive predictive coding (APC) to form an efficient speech coding system operating at bit rates of 16 and 9.6 kb/s. The effectiveness of t... 详细信息

CELP coding USING TRELLIS-CODED VECTOR QUANTIZATION OF THE EXCITATION
收藏 引用
IEEE TRANSACTIONS ON SPEECH AND AUDIO PROCESSING 1995年 第6期3卷 464-472页
作者: POPESCU, A MOREAU, N LAMBLIN, C TELECOM ParisTech Paris France LAA/TSS/CMC CNET Lannion France
We analyze the performance of a CELP coder where the vector quantization (VQ) of the excitation is replaced with trellis-coded vector quantization (TCVQ), Our results show that TCVQ performs significantly better than ... 详细信息

DEPTH-FIRST coding FOR MULTIVALUED PICTURES USING BIT-PLANE DECOMPOSITION
收藏 引用
IEEE TRANSACTIONS ON COMMUNICATIONS 1995年 第5期43卷 1961-1969页
作者: KAMATA, SI EASON, RO KAWAGUCHI, E UNIV MAINE DEPT ELECT ENGNORONOME 04469
A data compression technique using a bit-plane decomposition strategy of multivalued images is described, Although the bit-plane decomposition is mainly used for image transmission, our method takes the image expressi... 详细信息

1993 IEEE International Conference on Acoustics, Speech, and Signal Processing
作者: N. Balram J.M.F. Moura IBM Corporation Boca Raton FL USA Department Electr. and Comp. Engineering Carnegie Mellon University Pittsburgh PA USA
A novel image compression algorithm is presented. The algorithm combines the recursive processing characteristic of predictive coding with the use of a noncausal image model. Experimental results demonstrate the high ... 详细信息

International Conference on Acoustics, Speech, and Signal Processing (ICASSP)
作者: N. Magotra W. McCoy F. Livingston S. Stearns Department of EECE University of New Mexico Albuquerque MN USA Department9311 Sandia National Laboratories Albuquerque NM USA
The paper describes the application of adaptive filters in a two stage lossless data compression algorithm. The term lossless implies that the original data can be recovered exactly. The first stage of the scheme cons... 详细信息
