Tree Source Identification with the Burrows Wheeler Transorm
by D. Baron and Y. Bresler. Postscript paper describing a technique that uses BWT to preprocess a sequence of symbols, then mung.
Archive Converter
This freeware program is used to convert archives from one format to another. It says it supports “any archiver,” I guess you can’t ask for more than that.
Huffman.java
Advertises itself as “A dirty but free implementation of a huffman encoder/decoder in Java.” Not completely free, it is covered by the GLPL, and naturally includes fully documented source.

GeoEnergy, Inc.
Their home page advertises GeoEnergy as “The leader in fast data compression algorithms for the oil and gas industry.” Quite a few algorithms are listed, all of which work on various types of collected seismic data.
FileWrangler
Yet another file manager that knows how to work with GIF files.
An Experimental High Fidelity Perceptual Audio Coder Project in MUS420 Win 97
A paper describing an experimental audio coder developed as some sort of class project.
Data Compression Benchmark Suite
A set of links to files that are used to benchmark various data compression algorithms.
Fast Exponentiation Using Data Compression
Given the title, this paper has something to do with data compression. But I sure don’t get it.
Slashdot Interview With Jean-loup Gailly
Jean-loup talks about Llinux, data compression, patents, and more.
Zoran Corporation
Zoran makes chips that do some MPEG decoding as well as JPEG codecs.
DropZip by Aladdin Systems
A commercial program that supports both the Stuffit and Zip formats. DropZip is available for both Mac and Windows platforms.
ASPack - an Executable Compressor
Another program for compression executables. This is a Win32 preprocessor that claims to reduce EXE size as much as 70%.
IBM Research - Image application solutions
The image application group at IBM’s Watson Research Center works on quite a few different topics related to digital imaging, including image capture, color science, printing and displaying images, and so on. Of course, part of that is image compression, which is why we’re interested in them.
CabPack
A freeware program that you can use to create CAB files.
fastJar
fastJar is a C version of Sun’s jar utility. Being written in C instead of Java gives this program a bit of a boost; albeit at the expense of purity.
ZipCracker
A program that will help you figure out that zip password that you just can’t seem to recall. In a tarball.
ACM Crossroads Spring 2000 Issue - Data Compression
Crossroads is the student publication of the ACM. This issue concentrates on data compression, and includes several very worthwhile articles.
Java I/O and Comrpession by Matt Tucker
An article from the ACM Crossroads student publication. This article shows how to use some of the built-in classes in the JDK to create and access compressed files and streams.
An Error-Controlled Octree Data Structure for Large-Scale Visualization
An article in the Spring 2K issue of Crossroads, the ACM student publication.
Prefix Compression of Sparse Binary Strings
by David Salomon. This article discusses an approach to the unique problem of compression sparse binary strings.
Image Compression - from DCT to Wavelets : A Review
by Subhasis Saha. A survey paper on various techniques of image compression.
Efficient Quadtree Code: Spatial Linear Quadtree
Laurent Balmelli from the neutral country of Switzerland has some C++ code to do some interesting quadtree processing. He would like you register if you are going to use the code, but this is not mandatory. This code is being used by over 100 registered users, and has at least been accessed by as many […]

Mary Holly Johnson’s source code
Mary Holly Johnson wrote a couple of papers on something called ECVQ, which I’m guessing is a type of vector quantization. This ftp directory has a bunch of C code that probably implements the code from one or more of her papers.
Solution-Soft
Solution-Soft is the provider of software for online archiving and for bandwidth management in the Internet infrastructure and the enterprise. Solution-Soft’s products enable data files to be archived online and transferred faster over networks through a revolutionary technology providing transparent compression and decompression.
Pentamedia
Among other things, these folks make a MPEG 1/2 A/V encoder board for your PC. As an added bonus, their site comes in English, Spanish, and Korean versions.
Toshiba VideoPhone MPEG-4 IC
Toshiba announces silicon suitable for building an MPEG-4 based videophone. Pretty nice looking piece of work, shipping in Q42K.
The XYZ Algorithm For Real-Time Compression of Full-Motion Video
A new DCT based moving pictures compression algorithm. The authors claim results far superior to that of MPEG.
Note: this paper will cost you $35.00. Abstract only is free.
