Quality controlled ECG compression using essentially non-oscillatory point-value decomposition (ENOPV) technique
收藏 引用
DIGITAL SIGNAL PROCESSING 2012年 第6期22卷 878-884页
作者: Aggarwal, Vibha Patterh, Manjeet Singh Punjabi Univ COEM Rampura Phul Punjab India Punjabi Univ UCOE Patiala Punjab India
This paper presents an essentially non-oscillatory point-value (ENOPV) scheme based ECG compression. ENOPV scheme is a combination of multiresolution scheme (analysis) and interpolation scheme (synthesis). Advantage o... 详细信息

JOURNAL OF COMPUTATIONAL CHEMISTRY 2012年 第27期33卷 2131-2141页
作者: Marais, Patrick Kenwood, Julian Smith, Keegan Carruthers Kuttel, Michelle M. Gain, James Univ Cape Town Dept Comp Sci ZA-7925 Cape Town South Africa
We investigate whether specific properties of molecular dynamics trajectory files can be exploited to achieve effective file compression. We explore two classes of lossy, quantized compression scheme: interframe predi... 详细信息

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

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

ERGODIC THEORY AND DYNAMICAL SYSTEMS 2012年 第02期32卷 755-U466页
作者: Katok, Svetlana Ugarcovici, Ilie Penn State Univ Dept Math University Pk PA 16802 USA DePaul Univ Dept Math Sci Chicago IL 60614 USA
We describe a general method of arithmetic coding of geodesics on the modular surface based on the study of one-dimensional Gauss-like maps associated to a two-parameter family of continued fractions introduced in [Ka... 详细信息

15th IEEE International Conference on Image Processing (ICIP 2008)
作者: Grangetto, Marco Magli, Enrico Mo, Gabriella Univ Turin Dipartimento Informat I-10124 Turin Italy Politecn Torino Dipartimento Elettr Turin Italy
We propose a distributed source coding system for data collected by sensor networks. It uses a feedback channel between the sensors and the gateway node (i.e., the joint decoder) but, unlike previous systems, the enco... 详细信息
