Codecell convexity in optimal entropy-constrained vector quantization
收藏 引用
IEEE TRANSACTIONS ON INFORMATION THEORY 2003年 第7期49卷 1821-1828页
作者: György, A Linder, T Hungarian Acad Sci Informat Lab Comp & Automat Res Inst H-1518 Budapest Hungary Queens Univ Dept Math & Stat Kingston ON K7L 3N6 Canada
Properties of optimal entropy-constrained vector quantizers (ECVQs) Are studied for the squared-error distortion, measure. It is known that restricting an ECVQ to have convex codecells may preclude its optimality for ... 详细信息

PRINCIPLES OF QUANTIZATION
收藏 引用
IEEE TRANSACTIONS ON CIRCUITS AND SYSTEMS 1978年 第7期25卷 427-436页
作者: GERSHO, A UNIV CALIF LOS ANGELES DEPT SYST SCI LOS ANGELES CA 90024 USA
Quantization is the process of replacing analog samples with approximate values taken from a finite set of allowed values. The approximate values corresponding to a sequence of analog samples can then be specified by ... 详细信息

OPTIMAL QUANTIZATION OF THE RAYLEIGH PROBABILITY DISTRIBUTION
收藏 引用
IEEE TRANSACTIONS ON COMMUNICATIONS 1979年 第1期27卷 101-112页
作者: PEARLMAN, WA SENGE, GH Department of Electrical and Computer Engineering University of Wisconsin Madison WI USA Radar Systems Group Hughes Aircraft Company Culver CA USA
We have derived an efficient and general algorithm for optimal quantization and applied it to the important, but neglected Rayleigh random variable. The optimal quantization range and output levels for the distortion ... 详细信息

IEEE TRANSACTIONS ON INFORMATION THEORY 2012年 第5期58卷 2719-2728页
作者: Smieja, Marek Tabor, Jacek Jagiellonian Univ Inst Comp Sci Dept Math & Comp Sci PL-30348 Krakow Poland
Suppose that we are given two sources S-1, S-2 which both send us information from the data space X. We assume that we lossy-code information coming from S-1 and S-2 with the same maximal error but with different alph... 详细信息

Prioritized DCT for compression and progressive transmission of images
收藏 引用
IEEE TRANSACTIONS ON IMAGE PROCESSING 1992年 第4期1卷 477-487页
作者: Huang, Yunming Dreizen, Howard M. Galatsanos, Nikolas P. IIT Dept Elect & Comp Engn Chicago IL 60616 USA
In this paper a new approach based on the block discrete cosine transform (DCT) for compression and progressive transmission of images is presented. The novelty of this approach is that the transform coefficients of a... 详细信息
