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.
WMPhoto is a new format for image compression that is said to have better quality/compression ratio than that of current standards, including JPEG 2000. The main goal of this testing was the verification of superiority of WMPhoto by comparing it against nine JPEG 2000 codecs from last year's JPEG 2000 Image Codecs Comparison.

The RV-Media, a start-up company, offers its Jpeg2000 SDK as a software development kit intended to enable programmers to easily develope applications based on Jpeg2000 specification. The SDK contains an implementation of Jpeg2000 decoder. The encoder is claimed to be supported in future versions. Free 1.0.0 Alpha 1 version is available for download as of May 23, 2006; it supports decoding of Jpeg 2000 images from buffer or file, thumbnails extracting, viewing, export to BMP.

The aim of this paper is to improve the performances of the JPEG2000. In fact, the approach named PJPEG2000 consists in inserting a phase of pretreatment before initiating the JPEG2000 process. This investigation allows better quality compression. When compressing images, noise is fatal to compression performance, it can be both annoying for the observer and make transmission of the imagery consume excessive amounts of bandwidth. The pretreatment based on the filtering reduces noise and thus improve both visual impression and transmission properties. The comparison between JPEG2000 and PJPEG2000 shows that the latter is favourable in both PSNR and WPSNR and in visual inspection evaluation.

DataCompression.info user Tim A. gushed: A very fast implementation with a small memory footprint compared to Jasper and even other commercial implementations. Also handles large files better than all others I have tried. Very well done with motion JPEG2000, a viewer and a JPIP server to boot (and those are just the sample applications!). John J. added The best of any JPEG2000 compressors for lossless compression. Higher compression rates, and faster compression than Aware and Algo Vison Luratech.

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 http://www.crc.ricoh.com/~gormish/jpeg2000conformance/J2KP4files/ 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.
This product converts your photos to JPEG-2000 format to speed up the process of sending them by mail. And how do your friends view these photos when they get them? Well, it appears that AMC will be happy to give them a free JPEG 2000 viewer.
