Analysis of Arithmetic Coding for Data Compression
A paper by Howard and Vitter, available in both PDF and PS formats. The paper provides an analysis of the effect that models and various implementations of arithmetic coding have on compression.
Fractal Frequently Asked Questions and Answers
The Usenet newsgroup sci.fractals and the listserv forum frac-l are devoted to discussions on fractals. This FAQ (Frequently Asked Questions) is an electronic serial compiled from questions and answers contributed by many participants in those discussions. This FAQ also lists various archives of programs, images, and papers that can be accessed through the global computer […]

Surfing the Wavelets
A nice on-line paper that proposes to teach you a little something about wavelets.
Pixelon Bites the Dust
Pixelon shows what happens when technology gets mixed up with big bucks and shady characters. The Industry Standard ran a great story on it, but as they have gone belly up
this link may not work any more. So this CNet news article will have to do.
Reader Tim A. points out that they also claim that […]
Microsoft Cabinet Software Development Kit
The Cabinet Software Development Kit provides developers with the components needed to utilize Microsoft’s cabinet file technology within other applications, or to build cabinet file management tools. Microsoft is committed to making cabinet files an open technology.DCL User says: Easy implementation and works with memory mapped file too.

MPEG-FAQ Version 4.1
An MPEG FAQ that is either from Frank Gadegast or KeyJ Phade. Worth a look, answers a lot of questions.
MPEG-4 AAC
This article from EE Times talks about the changes made to the Advanced Audio Coding portion of the standard during the change from MPEG-2 to MPEG-4.
The New Canterbury Corpus
No details, but it appears to be a collection of files designed to represent a slightly wider range of modern applications.

Ross Arnold and Tim Bell, “A Corpus for the Evaluation of Lossless Compression Algorithms”, Proc. IEEE Data Compression Conference, Snowbird, Utah, March 1997.
CCITT standard images (Bilevel)
Images commonly used in compression tests are stored here in Sun raster format. At this time I believe that all you will find here are gray scale images.

Samuel H. Smith’s original Unzip code
This source code appears to be Samuel Smith’s original Unzip code. This eventually gave birth to the Info-ZIP project and its UnZip program. Sam was the pioneer, and I believe he did most or all of it on his own.
US Patent 4941193: Methods and apparatus for image compression by iterated function system
One of the earliest patents regarding fractal compression. Issued 10 July 1990, assigned to Iterated Systems.
US Patent 5065447: Method and apparatus for processing digital data
A fundamental patent for fractal image compression assigned to Iterated Systems. This patent was issued 12 November 1991.
US Patent 5347600: Method and apparatus for compression and decompression of digital image data
