Parallel lossless image compression using Huffman and arithmetic coding
收藏 引用
INFORMATION PROCESSING LETTERS 1996年 第2期59卷 65-73页
作者: Howard, PG Vitter, JS DUKE UNIV DEPT COMP SCI DURHAM NC 27708 USA AT&T BELL LABS RES VISUAL COMMUN RES HOLMDEL NJ 07733 USA BROWN UNIV PROVIDENCE RI 02912 USA
We show that high-resolution images can be encoded and decoded efficiently in parallel, We present an algorithm based on the hierarchical MLP method, used either with Huffman coding or with a new variant of arithmetic... 详细信息

Hierarchical dictionary model and dictionary management policies for data compression
收藏 引用
SIGNAL PROCESSING 1998年 第2期69卷 149-155页
作者: Yu, CL Wu, JL Natl Taiwan Univ Dept Comp Sci & Informat Engn Taipei 106 Taiwan
In this paper, an adaptive multi-dictionary model for data compression is proposed. Dictionary techniques applied in lossless compression coding can be modeled from the dictionary management point of view which is sim... 详细信息

Lossless and nearly-lossless compression of multispectral SPOT images
收藏 引用
Conference on Nonlinear Image Processing IX
作者: Mozelle, G Zaharia, T Preteux, F Cabot, F Inst Natl Telecommun Dept Signal & Image F-91011 Evry France
In this paper, we address the problem of lossless and nearly-lossless multispectral compression of remote-sensing data acquired using SPOT satellites. Lossless compression algorithms classically have two stages: Trans... 详细信息
