MT-WICE® - Wavelet based image compression

A proprietary image compression system using wavelets by MeVis Technology. Browser plug-ins available, naturally. Links to German language version of the page.

A DCL reader had this to say: Achieves high compression and has a useful interface. I have used only the non-registered version 2.6e
very powerful and probably superior to JWizard by Pegasus.

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.

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.
