A Short Course in Information Theory
8 lectures by David J.C. MacKay
January 1995. Cavendish Laboratory, Cambridge, Great Britain.
All of these lectures are available as PostScript files. The eight lectures cover data compression, coding, arithmetic coding, noisy channel coding, and much more
Lossless Compression of 3D MRI Brain Images
Typical clinical MRI scanners generate data on the order of about 200 MB each day. Because this data provides important diagnostic information, care must be taken in compressing it, and lossy compression is generally avoided. In this project we investigate different techniques for lossless compression of 3-dimensional MRI scans of the brain. These methods include […]

Altamira Group
These guys apparently make a couple of variations on a product called Genuine Fractals. The product is a Photoshop plugin that appears to read fractal file formats and do some sort of scaling. If this is a grotesque misrepresentation of what the product does, feel free to email a correction.
http://www.altamira-group.com/Mark Adler’s home page
Mark Adler has given much to us via his work on Info-ZIP, zlib, and PNG. Is he an interesting person as well? Here is the place to find out.
http://www.alumni.caltech.edu/~madler/Amara’s Wavelet Page
A lot of explanation of Wavelets on this page, along with some well-considered links. This site is often slow, and sometimes missing. Please be patient!
http://www.amara.com/current/wavelet.htmlalt.comp.compression
This newsgroup doesn’t generate as much compression as its sibling, comp.compression. I know of nothing else that differentiates the two.
news://alt.comp.compressioncomp.compression
This newgroup carries a good deal of interesting traffic on data compression. The lack of moderation means the noise level is still fairly high, but the interested reader can find much to enjoy here.

http://www.cs.waikato.ac.nz/~singlis/zlib - Looking the Gift Code in the Mouth
Mark Nelson’s zlib article, originally published in Dr. Dobb’s Journal. The source code for the article includes an OCX that allows you to use zlib from many different languages under Win32
If you are attempting to use the zlib OCX with Visual Basic or Visual C++, please follow the links to my FAQ. The OCX that […]

The Data Compression Reference Center
A site that provides some good pages discussing various fundamental aspects of Data Compression. Although the site appears to be a university project in Croatia, all of the pages are writen in English.

Data Compression Program for VM/ESA
DATA COMPRESSION PROGRAM for VM/ESA enables VM customers to automatially (sic) and transparently compress and expand CMS minidisk file data. This capability can help reduce DASD utilization, load on the I/O subsystem, and staff time spent managing minidisk space and “disk full” conditions.
From your friends at IBM.
