Mathematical Combinations and Compression
The comp.compression newsgroup regularly sees posts from folks with incredible compression claims. This one, started by Itai Bar-Haim, is remarkable not so much for its claims, but rather for the incredible length of the thread it spawned. All Atai said was that mathematical combinations have nothing to do with compression. So there.

On-Line Stochastic Processes in Data Compression
Suzanne Bunton’s PhD thesis. A recent post to comp.compression said that Bunton had used floating point math for arithmetic coding. I haven’t verified this, but it sounds worth a look.

Scalable Arithmetic Video Codec
This is a free codec that uses 3D-subband coding, progressive quantization and arithmetic coding. Based on work by David Taubman in pursuit of his PhD.
http://www-video.eecs.berkeley.edu/download/scalable/Crystal Net
These guys have a low bit rate video codec designed to transmit moving pictures over POTS lines, with associated products that take advantage of the code.

These folks make a product called MP Studio Pro, which is a compression/decompression engine, and seems to be geared towards content producers.

This French company seems to have some image compression software or service to offer. The web page seems to be entirely in French, although it has some misleading links with a UK flag that you might think meant an English language version was available. Native speakers of French are encouraged to improve on this description.
http://www.iso-informatique.com/Compression Technologies, Inc.
These folks make CinePak and CinePak Pro, which are digital compression tools based on the CinePak codec. They have applications that run on both MacOs and Windows.

The Qx-coder
IBM’s implementation of arithmetic coding known as the Q-coder is a well-known piece of work. (Patented, unfortunately.) This paper discusses an implementation of the Q coder in hardware.

This IBM research paper looks into the performance of compressors in relation to the compressibility of the the objects they are compressing. At least I think that’s what it is talkinga bout.
