Compression of Hyperspectral Scenes through integer-to-integer Spectral Graph transforms
收藏 引用
REMOTE SENSING 2019年 第19期11卷 2290-2290页
作者: Tzamarias, Dion Eustathios Olivier Chow, Kevin Blanes, Ian Serra-Sagrista, Joan Univ Autonoma Barcelona Dept Informat & Commun Engn Campus UAB E-08193 Barcelona Spain
Hyperspectral images are depictions of scenes represented across many bands of the electromagnetic spectrum. The large size of these images as well as their unique structure requires the need for specialized data comp... 详细信息

Reversible Resampling of integer Signals
收藏 引用
IEEE TRANSACTIONS ON SIGNAL PROCESSING 2009年 第2期57卷 516-525页
作者: Hao, Pengwei Univ London Dept Comp Sci London E1 4NS England Peking Univ Ctr Informat Sci Beijing 100871 Peoples R China
Except some extremely special cases, signal resampling was generally considered to be irreversible because of strong attenuation of high frequencies after interpolation. In this paper, we prove that signal resampling ... 详细信息

Generalized multiple description coding with correlating transforms
收藏 引用
IEEE TRANSACTIONS ON INFORMATION THEORY 2001年 第6期47卷 2199-2224页
作者: Goyal, VK Kovacevic, J Bell Labs Murray Hill NJ 07974 USA
Multiple description ND) coding is source coding in which several descriptions of the source are produced such that various reconstruction qualities are obtained from different subsets of the descriptions. Unlike mult... 详细信息

Matrix factorizations for parallel integer transformation
收藏 引用
IEEE TRANSACTIONS ON SIGNAL PROCESSING 2006年 第12期54卷 4675-4684页
作者: She, Yiyuan Hao, Pengwei Paker, Yakup Peking Univ Ctr Informat Sci Beijing 100871 Peoples R China Queen Mary Univ London Dept Comp Sci London E1 4NS England Peking Univ Ctr Informat Sci Beijing 100871 Peoples R China
integer mapping is critical for lossless source coding and has been used for multicomponent image compression in the new international image compression standard JPEG 2000. In this paper, starting from block factoriza... 详细信息

Optimal filter banks for multiple description coding: Analysis and synthesis
收藏 引用
IEEE TRANSACTIONS ON INFORMATION THEORY 2002年 第7期48卷 2036-2052页
作者: Dragotti, PL Servetto, SD Vetterli, M Swiss Fed Inst Technol LCAV EPFL CH-1015 Lausanne Switzerland
Multiple description (MD) coding is a source coding technique for information transmission over unreliable networks. In MD coding, the coder generates several different descriptions of the same signal and the decoder ... 详细信息

Integer polar coordinates for compression
收藏 引用
IEEE International Symposium on Information Theory
作者: Ba, Demba E. Goyal, Vivek K. MIT Cambridge MA 02139 USA
This paper introduces a family of integer-to-integer approximations to the Cartesian-to-polar coordinate transformation and analyzes its application to lossy compression. A high-rate analysis is provided for an encode... 详细信息

SAR Image Compression Using integer to integer Transformations, Dimensionality Reduction, and High Correlation Modeling
收藏 引用
Journal of Computer and Communications 2022年 第2期10卷 19-32页
作者: Sergey Voronin Independent Researcher Reston VA USA
In this document, we present new techniques for near-lossless and lossy compression of SAR imagery saved in PNG and binary formats of magnitude and phase data based on the application of transforms, dimensionality red... 详细信息
