TMR - Wavelets in Numerical Simulation
This page reflects the necessity of developping collaborations (and intensify those that already exist) between the nine research groups from six different european countries, with the ultimate common goal of applying wavelet-based methods to complex industrial problems.
A Review of Video Streaming over the Internet
A technical report giving an overview of various video streaming formats used in today’s Internt. Includes low-level details such as transport formats, and high-level info such as providers of application servers.

Microsoft Seeks to Depose MPEG-2
EETimes reports on Microsoft’s Corona encoder - a video encoder that is touted as being superior to MPEG-2. The movie business is in a quandry, faced with the technical demands needed to put HD movies on disk. Using conventional compression, they would need to convert to costly blue-laser driven systems. Microsoft offers them a way […]
SA-Comp/1 and SA-Comp/4 Data Compression SA

Hi/fn, Inc.
Hi/fn makes lossless compression hardware and software. They have a bunch of chips that implement LZS and MPCC compression, plus a library that does the same thing. I have been led to believe that these algorithms are partially or completely protected by patents.
SONARC: Digital Audio Compression, Version 2.1i
SONARC is an old DOS audio compression program that was apparently used in Ultima, a well known game.
The Context Tree Weighting Method: Basic Properties
One page poster for Frans M.J. Willems, Yuri M. Shtarkov, and Tjalling J. Tjalkens, “The Context Tree Weighting Method: Basic Properties,” IEEE Trans. Inform. Theory, May 1995. (Postscript)
Context Weighting for General Finite-Context Sources,
by Frans M.J. Willems, Yuri M. Shtarkov, and Tjalling J. Tjalkens, IEEE Trans. Inform. Theory, Sept. 1996. A postscript version of this overview paper.
Medical Image Format FAQ - Part 7
Lots of pointers here. Relevant to compression because of the wealth of pointers to various formats used in medical imaging, such as JPEG-LS and Lossless JPEG.
MELP Vocoder Algorithm
Atlanta Signal Processor, Inc., is nice enough to host his paper on their site. It gives a brief overview of the MELP Vocoder algorithm.
RICAZip.com
RICAZip.com has proprietary lossless image compression technology called RICA (Reversible Image Compression Algorithm). RICA retains original file formats (e.g. TIFF, DICOM, BMP, TGA, PGM etc.). RICACom says We have yet to find any method that provides better compression ratios (for truly lossless), including wavelet. On a PII 450MHz RICA compresses @ 6MB […]
Vector Quantization
Mohamed Qasem’s page dealing with VQ. A nice overview of what it’s all about, plus links to other sites and people in the VQ world.

aPlib Compression Library
32bit pmode compression library based on the algorithm used in aPACK. Both the library and some samples are included on this page.
Huffman encoding
The definition from Paul E. Black’s dictionary.
Lossless Compression of Grayscale Medical Images - Effectiveness of Traditional and State of the Art Approaches
The very long title of this PDF format paper pretty much obviates the need for any more description on my part.
Open Mash
The Open Mash Consortium supports the Mash streaming media toolkit and distributed collaboration applications based on the Internet Mbone tools and protocols. The consortium is funded by a grant from the National Science Foundation Internet Technologies Program (Grant ANI-9907994) and by contributions from consortium members.
Malcom Taylor’s Home Page
This link takes you to Malcom’s RKAU program, a lossless audio compressor. Malcom’s page says it often beats WA in max mode, at double the speed.
Code and Parse Trees for Lossless Source Encoding
A survey paper by Julia Abrahams.
ZFilter
ZFilter is the ZIP indexing filter for SharePoint, Internet Information Server, Site Server and Microsoft Exchange server. ZFilter is a library that handles .zip archives and returns indexable text and value properties in a similar way to the MS Office filter and the PDF filter supplied by Adobe. The library handles all zip archives created […]
LDZip
This product creates Zip files with long filenames under MS-DOS. It supports FAT32 and NTFS, and is designed to give you an easy way to back up your data when your Win32 machines decides not to boot. It’s Free!
A Two-Stage Modelling Method for Compressing Binary Images by Arithmetic Coding
A paper describing a compression scheme for bitonal images. Complete text of paper in compressed postscript.
Geoff Davis
Geoff Davis’s home page. Geoff has published several of his wavelet papers on the web, including an interesting analysys of Fractal compression in terms of wavelets. At one time Geoff Davis was responsible for a Wavelet toolkit, but it isn’t on his new site. Please forward pointers is you find it.
Compression Algorithms
A set of links from Softpanorama, the Open Source Software Educational Society. A lot of information on the entire site. The compression links are not as complete, but some interesting stuff here.
GIF89a Animation Browser Test
These pages will test the various features available for GIF89a animation. Each feature is tested as independently as possible, allowing you to identify what features your browser supports and how well. The pages isolate features to prevent combination collisions (one error causing another feature to fail). Each test is composed of an animation that tests […]
GIF87A Specification
This is a copy of the original GIF specification from CompuServe. It was expanded significantly by the 1989 specification.
GIF89A Specification
Additional GIF format documentation

Shorten Technical Report Simple lossless and near-lossless waveform compression
Technical report CUED/F-INFENG/TR.156 , Cambridge University Engineering Department, by Tony Robinson. A somewhat terse technical report describing some of the theory behind the design of the Shorten program.
U of F Says Compressing Medical Images Risky
A study at the University of Florida showed that even mildly compressing coronary angiograms led to an increase in diagnostic errors.
