Our technology served as the foundation for numerous voice compression products used by voice portal and large multinationals in their efforts to better meet the quality requirements that end users. As example voice email, voice chatting, voice annotation in web site. Our technology is already integrated into software by companies such as Microsoft with […]
http://www.voiceage.comPapers of Christos Chrysafis
Christos Chrysafis has quite a few papers on wavelets available here.
http://sipi.usc.edu/~ortega/Students/chrysafi/Rate Scalable Color Image Compression
Edward J. Delp describes his wavelet-based coding system for color images using a luminance/chromanance color space.
http://dynamo.ecn.purdue.edu/~ace/color-wavelet/cwavelet.htmlA Rate Scalable Video Codec
Edward J. Delp and pals have created a rate-scalable video codec that uses a wavelet based codec with motion compensation.
http://dynamo.ecn.purdue.edu/~ace/wavelet/wavelet2.htmlParallel Video Compression
Edward J. Delp et.al. have tackled the problem of perfomring video compression using parallel processing techniques.

Avideh Zakhor has links to many of her papers on image compression.
http://www-video.eecs.berkeley.edu/~avz/Strmat
A collection of C programs that do string matching and pattern discovery. This appears to be free code by D. Gusfield, who also has a book called “Algorithms on Strings, Trees and Sequences: Computer Science and Computational Biology”.
One DCL reader commented The strmat package is wonderful.
MPEG LA
This company is the licensing authority created by the owners of the most or all of the patents related to MPEG. Apparently they have the authority to provide one-stop shopping for your royalty arrangements.

Interpolative Coding at 2.8 kbps
These folks at UCSB are encoding speech at 2.8 Kbps. It sounds very good considering the bit rate. Links here to a presentation and an abstract, as well as some samples.
http://scl.ece.ucsb.edu/current/oded/ewi_demo.htmTiling and Adapative Image Compression
This paper appears to discuss the concept of compressing images by breaking them down into small pieces and doing some sort of optimal compression on each piece. I assume the trick here is to locate the point of diminishing returns.
