Jesper Larsson

Jesper Larsson spent a fair amount of his years in academia
studying Suffix Trees. His home page has links to his thesis and a few other papers on suffix trees and other string matching/Data Compression topics.

Dmitry Shkarin

Dmitry Shkarin is the author of the PPMD compressor. His homepage has links to to versions A-I of the compressor as of April, 2003. This page is in Russian, but I find that running it through
BabelFish produces a usuable translation.

David Taubman

Published in People, JPEG-2000

David Taubman is on the faculty of the University of New South Wales, in Sydney, Australia. Taubman is the author of the book JPEG2000: Image Compression Fundamentals, Standards and Practice and has been very influential in the current development of the standard. He is also the author of Kakadu, a commercial library that is advertised as a complete implementation of Part 1 of the standard.

Context Tree Weighting

Context Tree Weighting (CTW) has been a technique with great promise, but it hasn’t ever been able to reach the critical mass needed to become more than a curiousity. Jürgen Abel is doing his best to overcome that problem. He’s created a nice reference page for CTW on his data-compression.info web site. He has references to a few papers, a few people, and one piece of source code.

Burrows-Wheeler Transformation / Block Sorting (BWT)

Jürgen Abel has done an enormous amount of research on the Burrows-Wheeler Transform, and has published the results on his web site. On this page you will find:

  • A summary of this compression technique.
  • Links to over 70 online papers.
  • Links to at least that many people involved in BWT research or development.
  • Extensive links to BWT source code.

This web page may now be the definitive source of information for this field.

Daniel Lemire

Daniel Lemire is a researcher at the National Research Council of Canada. Some of his recent research interest is on wavelet-based prefix sum methods for On-Line Analytic Processing (OLAP). Some of his publications are relevant to compression techniques including a white paper on image compression by wavelets.

Florida Compression Scheme Nets Millions

This isn’t a new story, but the Florida Times-Union of Jacksonville gives a lot of detail in this treatment. A fellow named Madison Priest seems to have pulled in millions with his promises of hardware that can push high quality movies over conventional phone lines. Lots of interesting details, including the famous coax line hidden in the power cord! The second part of this story can be found
here.

The $5000 Compression Challenge

Patrick Craig has an interesting tale to tell. Without being a data compression expert, he managed to beat the $5000 compression challenge. You won’t see him taking an ocean cruise with his winnings, though. DCL reader commented: The challenge was obviously met.

Paolo Ferragina

Paolo Ferragina’s research in data structures and string matching naturally lends itself to Data Compression and to the problem of indexing compressed data. See the link to his recent papers on indexing BWT compressed files. He is currently an Associate Professor of Computer Science at the University of Pisa.

Shannon Statue

A bronze statue of Claude Shannon will be unveiled on Friday, October 6, 2000 in his hometown, Gaylord, Michigan. This sculpture by Eugene Daub was commissioned by the Information Theory Society of the Institute of Electrical and Electronics Engineers (IEEE). It will be installed in the recently named Shannon Park in downtown Gaylord.

SPACL

The Signal Processing and Coding Laboratory (SPACL) at The University of Arizona has some papers on line, plus some information on their current projects. They seem to be interested in wavelets, quantization, and signal coding.

A DCL reader complained: Very little useful information on the website. On topic, but not helpful at all.
