JPEG 2000: IRIS-JP3D software
Publication date 02.08.2011
Seeding research and industry
The Joint Photographic Experts Group (JPEG) is a subcommittee of the International Organization for Standardization (ISO). This group is well-known for the JPEG standard which originated there and is embedded in a plethora of devices as the compression standard for digital images. Every digital camera available today supports this technology by default.
In 2000, the JPEG committee published the successor of this standard, JPEG 2000. This new standard offers improved compression efficiency and enables additional functionalities such as resolution and quality scalability, random spatial access and others. Until now, JPEG 2000 has been a real success in specialized markets such as digital cinema, surveillance & security and medical imaging.
For the medical imaging market, a volumetric extension (JPEG 2000 Part 10) to the standard was defined, which enables the efficient compression of image data sets originating from medical scanners such as CT, MRI and PET. The Department of Electronics and Informatics (ETRO) of the Vrije Universiteit Brussel and the Interdisciplinary Institute for Broadband Technology (www.ibbt.be) chaired Part 10 of the JPEG 2000 standard and provided the main technological components and software for it.
The IRIS-JP3D software is a functional implementation of Part 1 (2-D) and Part 10 (volumetric) of the JPEG 2000 standard. The codec is written in ANSI/C in order to allow compilation on a large set of different platforms, in such a way that the applied algorithms are easily recognizable in the source code. The code forms a great starting point for researchers, students, and private companies who need to learn more about the JPEG 2000 compression technologies and who wish to design proprietary implementations for integration into their products. The software is available under both research and commercial licenses.
