Compression Technologies, Inc.
These folks make CinePak and CinePak Pro, which are digital compression tools based on the CinePak codec. They have applications that run on both MacOs and Windows.
ISO Informatique
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.
Motion Pixels Company
These folks make a product called MP Studio Pro, which is a compression/decompression engine, and seems to be geared towards content producers.
Crystal Net
These guys have a low bit rate video codec designed to transmit moving pictures over POTS lines, with associated products that take advantage of the code.
Scalable Arithmetic Video Codec
This is a free codec that uses 3D-subband coding, progressive quantization and arithmetic coding. Based on work by David Taubman in pursuit of his PhD.
Video Compression and Transmission over Best-effort Datagram Networks
by Wai-tian Tan and Avideh Zakhor . The title of the paper says it all, I think.
A free C++/MFC source code image framework with jpeg and dib codecs
Free MFC source code for displaying JPEG files. Completely free, can be used in commercial products.DCL User Comment: Very slow and awkward to work with…
DWIT Video Codec Homepage
To quote the page: The DWIT video codec is a real-time Differential Wavelet Integer-based Transform software video codec that runs on SGI Octane and O2 workstations. The codec is written in C++ and is distributed under GNU Copyleft.
AIPNL data compression pages
Information on: UC2 ARC ARJ LZH RAR ZIP UCRYPT JPEG MPEG etc. I think AIPNL makes UltraCompressor.
Plain Simple Zip 1.0
A cheap shareware program that performs your basic Zip and Unzip functions.
LHA Compression
This page has a good set of pointers to LHA programs and source code, including variants such as AR002, lz_comp2, and Lharc.
Data Compression Links from Epsilon Coder
Links that mostly point to some papers and source code, concentrating on lossless LZ type compression.
Compression Engines, Inc.
Compression Engines, Inc. has a file format called WIF, which stands for Wavelet Image Format. They licensed it from HARC, and have created and ActiveX control, a browser plugin, a standalone program, and the requisite Photoshop plugin. Check it out.
Zlibc
Zlibc emulates a compressed file system. This lets you keep all your executables compressed in one place, unzipping them on the fly as they are needed. Looks like it works with various Linux and UNIX type sytems, including Solaris. I’m guessing that it’s free, please correct me if I’m wrong.
Data Compression Technology by Compris.com
These folks appear to be selling some lossless compression technology, but I’m not quite able to determine what it is.
Geolytics
This company appears to be in the business of packaging demographic data for research and commercial interests. As part of that, they apparently have some technology for performing some compression on the data sets.
GT Technology
This site advertises a bunch of nifty looking codecs, including TELP, JPEG, Speech, MPEG, and wavelet compressors. I can’t quite determine exactly what form the products come in.
Tiernan Communications, Inc.
These folks sell a couple of boxes that do MPEG-2 encoding. Looks like they are oriented towards the video broadcasting business.
Nuera Products
Nuera makes a couple of speech multiplexers that use CELP compression. You probably won’t be interested in these unless you’ve got a T1 line that is bursting at the seams.
Vladimir Valenta’s Home Page
Vladimir has pointers to a batch of his papers here, which seem to concentrate on image compression, including VQ and Wavelet based compression. Plus many links to image compression, fractal, and wavelet pages.
TSBK01 Image Coding and Data Compression
A course being given by the Image Coding Group at Linköping University. Contains a few useful links plus some course material.
A fast hardware data compression algorithm and some algorithmic extensions
A paper by D.J. Craft discussing findings from some research on lossless compression algorithm.s
Data compression technology in ASIC cores
A paper from the IBM R&D group discussing the use of lossless compression in hardware.
A JBIG-ABIC compression engine for digital document processing
A paper describing the creation of a compression engine that was later implemented in firmware.
Performance as a function of compression
This IBM research paper looks into the performance of compressors in relation to the compressibility of the the objects they are compressing. At least I think that’s what it is talkinga bout.
DC Micro
Home page for DC Micro, home of Crusher!, the data compression toolkit
The Qx-coder
IBM’s implementation of arithmetic coding known as the Q-coder is a well-known piece of work. (Patented, unfortunately.) This paper discusses an implementation of the Q coder in hardware.
Integrating the MPEG-2 subsystem for digital television
An IBM research paper. The title pretty much says it all.
IBM Journal of R&D - Vol. 43, No. 4, 1999 - Digital multimedia technology
This issue of the IBM Journal is packed full of articles about MPEG-2.
Data Compression Conference 1999 - Proceedings
All of the papers from the 1999 Data Compression Conference are available here on line. Yes, there is a catch - you will have to pay if you want to do more than read the abstract. (Looks like a strong incentive to become a member of the IEEE Computer Society.)
