UCF VLSI and Data Compression Lab
The University of Central Florida Data Compression Lab has a lot of interesting stuff here. More than just academic papers, for example the M5 online compression utility!.
http://vlsi.cs.ucf.edu/M5 Online Compression Utility ver 1.0.1
The University of Central Florida has this web page which allows you to upload a file and then compress it using a wide variety of algorithms.
http://vlsi.cs.ucf.edu/upload.htmlLatest Publications from UCF
Latest compression papers here. When this site was first crawled, the papers covered a wide variety of topics in both lossless and lossy compression.
http://vlsi.cs.ucf.edu/listpub.htmlACDZip
ACDZip is a zipping and unzipping program that gives you the power to compress image, audio, video and document files. It includes fast image previews and is ideal for opening zip files, backing up files, saving hard disk space, preparing files for distribution and protecting them with encryption and passwords.

Boost CRC Library
The Boost project is designed to put very high-quality peer-revied libraries in the hands of you and me. CRC checking has nothing to do with compression per se, but it is frequently used when archiving to validate results.

This paper from Jürgen Abel and Bill Teahan presents several preprocessing algorithms for textual data, which work with BWT, PPM and LZ based compression schemes. The algorithms need no external dictionary and are language independent. The average compression gain is in the range of 3 to 5 percent for the text files of the […]

Video Codec Design
Web page for a new book, Video Codec Design, to be published by Wiley in March 2002. Video Codec Design takes a design-based approach to image and video compression. The book covers the JPEG, JPEG2K, MPEG1/2/4 and H.261/3/L standards and gives detailed guidance on designing image and video compression applications.
