Iris Software


IRIS-JP3D is a functional implementation of Part 1 and Part 10 of the JPEG 2000 standard. It is developed by the Department of Electronics and Informatics (ETRO) of the Vrije Universiteit Brussels (VUB) and the Interdisciplinary Institute for Broadband Technology (IBBT).

Software codec

The codec is written in ANSI/C, in order to allow compilation on a large set of different platforms.

IRIS-JP3D was initially created to serve as the reference software for JPEG 2000 Part 10. Thus, it provides a functional, complete, high-quality, and extremely comprehensive implementation of both JPEG 2000 Part 1 and Part 10 that is open to scientific research.

The codec is written such that the applied algorithms are easily recognizable in the source code. By doing so, it tries to match the source code and the JPEG 2000 specifications as closely as possible, without jeopardizing the readability of the source code. Thus, the code forms a great starting point for researchers, students, and private companies that need to learn more about the JPEG 2000 compression technologies, both 2-D (Part 1) and 3-D (Part 10).

The IRIS-JP3D codec is designed to conform to Profile-1 of the JPEG 2000 Part 1 specification. Moreover, by delivering high-quality code-streams that have highly optimized rate-distortion characteristics, the IRIS-JP3D can, in that respect, compete with other commercial implementations.
