Abstract (English)

This European project contributed to the standardization process of JPEG2000 by addressing some particular issues and coordinating European efforts. JPEG2000 is the next generation ISO standard for compression of still images that is under development at the ISO/IEC JTC1/SC29/WG1 committee (also known as JPEG), to which all SPEAR partners contribute. The new standard will bring new functionalities and new performance to still image coding to address the requirements of today's and tomorrow's application needs. Current standards, such as JPEG, fail to meet such requirements. The main goal of this project is to address some of the issues that have not yet been appropriately addressed by JPEG. These issues are file format and requirements imposed by security techniques such as digital watermarking. The suitability of the existing SPIFF file format, which is an ISO standard (JPEG part 3), and the FlashPix file format, which has been developed by Kodak and adopted by the Digital Imaging Group, will be studied, as well as the possible necessary extensions for JPEG2000. EPFL in particular tested its digital watermarking techniques for suitability in JPEG2000 and studied which requirements it places on the file format, as extra information. This project also coordinated European efforts on the standardization of JPEG2000 and ensured that European interests and needs are properly addressed.
