Lycos - Computers/Algorithms/Compression/
A page of links on the Lycos portal.
Compressing Sparse Matrices
Some pseudo-code describing a way to maintain sparce matrices.
Lycos - Computers/Software/Data Compression/
The Lycos portal page of links to data compression software. All the usual suspects are here, such as PKWare, along with some others you might have missed.
xPress - Cross Platform File Compression
These guys appear to be selling a conventional file compressor that works on quite a few different desktops and mainframes. The product description on the web page manages to obscure the facts with a lot of marketing-ese, so I’m a bit fuzzy on the details.
Standard Speech Codecs
Descriptions of various speech codecs, include G.711, G.721, GSM, and CELP. Each codec gets a brief description plus pointers to additional material and source code.

Pin-Outs Algorithms : Compression
This portal site has a page dedicated to compression, plus a number of sub-pages with pointers to companies, researchers, and a few other odds and ends.
Optivision
This company says they are a big name in the world of network streaming video. Products on their web side seem to be oriented towards MPEG.
Zapex
Zapex makes chips, chip cores, and boards dedicated to real time compression, including MPEG-2 and AC3.
Sorenson Vision
Sorenson makes hardware and software for video conferencing and other video streaming apps.
Efficient stochastic source coding and an application to a Bayesian network source model
by Brendan J. Frey and Geoffrey E. Hinton. A new algorithm for generating efficient codes.
EPWIC: Embedded Predictive Wavelet Image Coder
A grey-scale wavelet compressor written in C. Includes pointers to source code and the paper presented on this work.
Pierre Moulin’s Papers
Pierre Moulin has authored quite a few papers on video and image compression. Unfortunately, the full text is available for only a few papers. Perhaps you could send Pierre an email asking him to put more stuff online.
Wavelets: Software and Applications
PhD thesis by Geert Uytterhoeven. PS version might be in German.
IVS
An Internet-based video conferencing system. Why is it interesting to us? It apparently includes an H.261 codec.
ZipWrangler
Another Win32 archving program. The pgogram is free if you are willing to view ads, o/w $12.
Optimized Morse Armor
John Savard develops an algorithm for optimally encoding messages when forced to use nothing but Morse code.
Modifications of the Burrows and Wheeler Data Compression Algorithm
by Balkenhol, Bernhard; Kurtz, Stefan; Shtarkov, Yuri M. The authors discuss some statistical qualities of BWT output and improve on the algorithm’s performance. This paper was presented at the 1999 Data Compression Conference.

Data Compression Algorithms
by Jeffrey N. Ladino. His description of the page: This page is a research project in the field of data compression algorithms. It is intended to be an informative overview for a beginner in the field of computer science. Mostly talks about lossless compression, with an explanation of Huffman coding.

Juergen Schmidhuber’s Publications
Juergen writes a lot of papers. Lots and lots of papers. Looks like lots of stuff on neural nets and the like.
TwinVQ
An audio compression format invented at NTT’s Cyber Space Laboratories. Get your player and compressor right here. (English avaible by following the sharp-eyed link.)
WIS Technologies, Inc.
WIS Technologies sells software (both standalone and plugins) to perform various types of compression, including wavelet and DCT based lossly algorithms. In addition, they seem to be moving into the hardware business with the announcement of an ASIC JPEG2000 codec.
Data-compression.com
The title says A website devoted to the principles and practices of data compression. Can’t ask for anything better than that. Appears to be run by Nam Phamdo from SUNY Stony Brook. Links to papers, explanations, and software.
User comment:Gives technical explanations and animated examples of a small number of compression methods. The explanations are […]
Theory of Data Compression
A nice overview of the field by Nam Phamdo, slanted a bit towards the academic view but at a very accessible level. Links to important and influential papers.
Lossless Data Compression
An overview of the topic by Nam Phamdo, with some basic definitions, plus a look at Huffman coding and LZ78/LZW coding.
