JJ2000

JJ2000 is the Java reference implementation (part 5) of JPEG 2000. This project was the result of a partnership between EPFL, Canon Research France and Ericsson. It ended in September 2001 with a complete implementation of the normative parts of the JPEG 2000 core coding system (part 1).

The JJ2000 website provides, at one hand, with some documents, papers and tutorials on JPEG 2000 and, at the other hand, with a JPEG 2000 codec. Both source-code and binaries are available for download. The last official release of the codec was version 4.1.

Installation and usage instructions

JP2 file format

Complete JP2 file format support:

A minimal JPEG 2000 decoder simply handles JPEG 2000 part 1 codestreams. However a codestream only contains compressed data and is not able to carry side-information such as intellectual property rights or color-spaces for correct display. For such cases, the JPEG 2000 standard defines a minimal file format, denominated as JP2, that encapsulates JPEG 2000 codestreams, whilst providing room for storing application specific data (i.e. metadata).

The last official JJ2000 codec (version 4.1) does not fully support this file format and is, for instance, not able to handle palletized images or restricted ICC profiles defined in JP2.

For a complete support of the JP2 file format, you will have to use the Eastman Kodak's patch. This patch was originally developed for JJ2000 4.1 and is now part of the JJ2000 5.1 and later versions.

Graphical User Interface:

This tool is a graphical front-end to the (command-line driven) JJ2000 5.1 codec. It is developed by the Swiss Federal Institute of Technology (EPFL) in the framework of the 2KAN European project.

The GUI is written in pure Java (1.4) and intends to provide with a more intuitive access to most of JJ2000's command line options (See the readme file for more details). Furthermore is embedded, for testing purpose, a security module that implements the EPFL's technology proposal based on document [1] and currently discussed in JPEG 2000 part 8.
