Rate-compatible distributed arithmetic coding
收藏 引用
IEEE COMMUNICATIONS LETTERS 2008年 第8期12卷 575-577页
作者: Grangetto, Marco Magli, Enrico Tron, Roberto Olmo, Gabriella Univ Turin Dept Informat Turin Italy Politecn Turin Dept Elect Turin Italy Johns Hopkins Univ Vis Lab Ctr Imaging Sci Baltimore MD USA
Distributed arithmetic coding has been shown to be effective for Slepian-Wolf coding with side information. In this letter, we extend it to rate-compatible coding, which is useful in presence of a feedback channel bet... 详细信息

IEEE COMMUNICATIONS LETTERS 2007年 第11期11卷 883-885页
作者: Grangetto, Marco Magli, Enrico Ohmo, Gabriella Politecn Torino Dipartimento Elettr I-10129 Turin Italy
We propose a distributed binary arithmetic coder for Slepian-Wolf coding with decoder side information, along with a soft joint decoder. The proposed scheme provides several advantages over existing schemes, and its p... 详细信息

Simultaneous arithmetic coding and Encryption Using Chaotic Maps
收藏 引用
IEEE TRANSACTIONS ON CIRCUITS AND SYSTEMS II-EXPRESS BRIEFS 2010年 第2期57卷 146-150页
作者: Wong, Kwok-Wo Lin, Qiuzhen Chen, Jianyong City Univ Hong Kong Dept Elect Engn Kowloon Tong Hong Kong Peoples R China Shenzhen Univ Dept Comp Sci & Technol Shenzhen 518060 Peoples R China
Based on the observation that iterating a skew tent map reversely is equivalent to arithmetic coding, a simultaneous compression and encryption scheme is proposed in which the chaotic map model for arithmetic coding i... 详细信息

NEW METHODS FOR LOSSLESS IMAGE COMPRESSION USING arithmetic coding
收藏 引用
INFORMATION PROCESSING & MANAGEMENT 1992年 第6期28卷 765-779页
作者: HOWARD, PG VITTER, JS BROWN UNIV DEPT COMP SCIPROVIDENCERI 02912 USA
We give a new paradigm for lossless image compression, with four modular components: pixel sequence, prediction, error modeling, and coding. We present two new methods (called MLP and PPPM) for lossless compression, b... 详细信息

Comments on "A Novel Compression and Encryption Scheme Using Variable Model arithmetic coding and Coupled Chaotic System"
收藏 引用
IEEE TRANSACTIONS ON CIRCUITS AND SYSTEMS I-REGULAR PAPERS 2008年 第10期55卷 3368-3369页
作者: Zhou, Jiantao Au, Oscar C. Hong Kong Univ Sci & Technol Dept Elect & Comp Engn Hong Kong Hong Kong Peoples R China Univ Illinois Urbana IL 61801 USA
Recently, Bose and Pathak proposed a joint compression-encryption scheme by incorporating an adaptive arithmetic coder with a coupled chaotic system [1]. In this comment, we first show that the scheme proposed by Bose... 详细信息

The design of an arithmetic coding mechanism to determine relationships in a hierarchy
收藏 引用
COMPUTERS & MATHEMATICS WITH APPLICATIONS 1999年 第9期37卷 61-71页
作者: Liaw, HT Shih Hsin Univ Dept Informat Management Taipei 116 Taiwan
In this paper, a dynamic user hierarchy mechanism based on arithmetic coding is proposed. Through careful design of keys, some economic keys are obtained. In our scheme, the relationship between two users can be easil... 详细信息
