| Wavelets area, Lossy area, ImageCompression area, SourceCode content, NonCommercialProgs content, NonCommercialLibs content | EPSILON is an open source wavelet image compressor. The project is intended for distributed and robust image processing. Created: 09/06/2007 |
| Zlib area, Lossy area, SourceCode content | Visual Studio 2005 projects for native ZLib and managed C# wrappers. From the home page: OpenNETCF provides a "port" of the zlib 1.2.3 library for Windows CE-based devices, including Pocket PCs, SmartPhones, Windows Mobile devices as well as the entire realm of generic Windows CE devices. We provide the full original source, modified slightly for the CE build environment, along with Microsoft Visual Studio 2005 Solution and Project files and compiled binaries for ARMv4 and ARMv4I for CE 4.2 and CE 5.0. We have also stripped out all of the makefiles and project trees that are not relevent to Windows CE development. If you are looking for those, we recommend that you visit the origin.

| Audio area, Lossy area, MP3 area, NonCommercialProgs content |
Everybody know, that MP3 CANNOT be compressed (commonly on MP3 forums some guys offer genius idea to use zip for MP3 collection, but moderators stop such stupid threads before all other guys describe such ideas level). Common compression ratio for MP3 files is 1:1.01 even for very good compressors. This utility allows to compress with ratio 1:1.2! Let's test it! Created: 31/05/2006 by Dmitriy Vatolin |
| Lossy area, Papers content | by A.Ratushnyak. A short discussion related to the compression of audio and pictures. A Library readher had this to say: Worth reading 2 or 3 times. Created: 18/03/2001 by Mark Nelson |
| Audio area, Lossy area, ImageCompression area, Courses content | The term "Multimedia" obviously covers a lot of different topics. Compression is one of them, and there is certainly a great deal to learn about compression and media formats at this conference. Created: 24/02/2002 by Mark Nelson |
| Tutorials content, Lossy area | This Wikipedia entry describes lossy data compression. In addition to a nice overview, includes links to many lossy compressors for still image, moving image, music and sound. Created: 27/01/2002 by Mark Nelson |
| Lossy area, German language, Papers content | A study of lossy compression algorithms, including discussion of JPEG, MPEG, and the DCT. Created: 24/12/2001 by Mark Nelson |
| Lossy area, BenchmarksTests content | A study at the University of Florida showed that even mildly compressing coronary angiograms led to an increase in diagnostic errors. Created: 05/12/2001 by Mark Nelson |
| Lossy area, Papers content | Wil Osberger has published a bunch of papers dealing the perceptual image assessment. You can see most of them here. While this isn't strictly a compression topic, it is obviously of critical importance to lossy compression techniques. Created: 04/07/2000 by Mark Nelson |
| Lossy area, Companies content | 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. Created: 23/03/2000 by Mark Nelson |
| JPEG area, Wavelets area, Lossy area, Fractal area, Companies content, Links content | The University of Bath has a group that is advertised as "world leaders in still image and video coding." They appear to be interested in lossy compression based on DCT, Wavelets, and Fractal compression. This is their home page. Created: 23/11/1999 by Mark Nelson |
