data compression link collection


JPEG2000 is intended to be a new and improved image compression method that replaces both JPEG and JBIG. This next big thing uses wavelets as the basis for both lossy and lossless algorithms.

From the site: Epic24 is a GUI program that I wrote to interactively compare graphic compression codecs against each other. It currently contains JPG, Lossless JPG, JPEG 2000, (Jasper Library Implementation), PNG, John Robinson’s BTP and ATP, and finally my own lossless graphics compression called IMPLODE (IMage Predictive LOssless Decoder Encoder).

RomSoft JPEG2000 libraries and plugins

JPEG200 products provided by RomSoft. Here you find a C++ DLL implementation of JPEG2000 Part 1 standard (ISO/IEC 15444-1) and a Photoshop plugin for JPEG2000 and J2K files

Reader Petrut D. had this to say:

One of the fastest JPEG2000 codecs out there. The Intel IPP library helped a lot with performance. I also tried the Photoshop plug-in, and managed to open all the test files from part 0 and part 1. The plug-in handled JP2 and J2K images from 1 bit to 16 bit signed/unsigned flowlessly. Highly recomend the C++ DLL and the Photoshop plugin.

JPEG 2000 Tools 2.0

Developed in the scope of MIGRATOR 2000 project (, this site presents a graphical user interface to the three currently available codecs (VM, JJ2000, Jasper) as well as validation and parsing services to J2k codestreams and JP2 files.
It’s currently a widely used tool within WG1 (JPEG) to perform compliance tests on coders and codestreams. Site requires free registration for purposes of tracking stored images.
