Home page for the members of the JBIG committee, as well as a place for links and information about the Bi-Level Image coding standard.

A straightforward article with some discussion and links.

Jasper is a C-language implementation of the JPEG-2000 Part-1 standard. Michael Adams seems to run the show, with help from Image Power and a small team. This page gives you access to the software, documentation, and a nice set of links. Jasper is distributed under a free license.

Version 1.701.0 is shipping as of February, 2004.

Developed in the scope of MIGRATOR 2000 project (www.migrator2000.org), this site presents a graphical user interface to the three currently available codecs (VM, JJ2000, Jasper) as well as validation and parsing services to J2k codestreams and JP2 files.
It’s currently a widely used tool within WG1 (JPEG) to perform compliance tests on coders and codestreams. Site requires free registration for purposes of tracking stored images.

A very comprehensive page of links from Yuval Fisher, who is right there in the middle of the whole fractal business. This page features a glut of links to papers, bibliographies, books, conferences, and software. You can’t go wrong here.

From the launch:

Hello, and be welcome to ReallyRareWares, a site for researchers (or nostalgic people like me) that miss the old days of multimedia encoding. Here you’ll find reviews and history of old software (encoders and decoders), deceased codecs (VQF, ePAC), oddities (AUPECg2, Astrid AAC), and so on, as well as downloads.

The folks at BitJazz maintain a nice list of links to data compression directories. That makes this page sort of a meta-directory.

A nice collection of pointers and links to audio/music compression software.

This site is dedicated to discussion and explanation of HTTP compression with the Apache web server. Looks to me like the first place to go for information.

Welcome to the WWW home page that describes Set Partitioning in Hierarchical Trees (SPIHT): the powerful new wavelet-based image compression method.

http://www.cipr.rpi.edu/research/SPIHT/

Current research projects in our lab include research into vector quantization (VQ), wavelets, image compression, edge detection using VQ, VQ for image browsing, VQ design for noisy channels, halftoning, and color palette management.

David Cary is a major link farmer. One of the sections of his massive Data Compression page has links to various images and files that are used in various benchmarks.

I am a graduate student (doktorand) in algorithms and data structures at the Department of Computer Science at Lund University. Special interests are text searching and data compression.

I use the links on this page to papers, but don’t index the page itself

QuickTime 6 was an early adopter of MPEG-4 technology, and they seem to be big believers in the standard. This is in contrast to Microsoft’s Windows Media 9, which uses proprietary codecs to compete with the open standards of MPEG-4. The MPEG-4 standard uses AAC for encoding audio, and Apple has a site
with a few links and information about this audio encoder. Alas, they
don’t have a date when AAC will be included in the iPod!

Links to code and tools to create random numbers. Quite useful, and includes some intriguing use of sound cards to provide true (instead of psuedo-random) numbers. Registration required.

Marco Schmidt has assembled a nice page of links and information on the Zip archive format. A few good links, but this isn’t the comprehensive guide you need to answer any question about the format.

This FAQ provides good information about various audio file formats, which naturally includes quite a few compressed formats. It also has a few links to other relevant pages.

Dmitry Shkarin is the author of the PPMD compressor. His homepage has links to to versions A-I of the compressor as of April, 2003. This page is in Russian, but I find that running it through
BabelFish produces a usuable translation.

The JPEG 2000 committee uses this as the main source of links to the JPEG 2000-related pages on their site. It also includes a friendly plug for a book by committee members, with a “Buy Me” link to Amazon.com.

A comprehensive set of compression pointers. Unfortunately, Michael is using some sort of software that makes bookmarking into his index impossible. So instead, you must link to the main page, shown here, and locate the links to “Data Compression”. Under that he has links to General Resources, Software, and Theory.

The American Mathematical Society runs a monthly column called ‘What’s New In Math,” featuring topics of general interest to their readers. In October 2002, the topic was data compression, which led to a fairly lengthy column with many, many references. Good reading!
