FP5 IST-2001-34096, 2KAN, “(JPEG)2K Advanced Networking” (2002-2004) The JPEG 2000 Open Standard concept goes beyond image compression only. Parts 1 and 2 concern basic technical elements for image compression and file format, Part 3 provides a solution to extend Parts 1 and 2 to motion, Part 4 and 5 are technical complements while Part 6 addresses mixed raster images. A new set of 4 Parts has recently been initiated thanks to an intense European activity. The 2KAN project has addressed all 4 new Parts (Part 8 JPSEC – Security, Part 9 – interactivity JPIP, Part 10 Floating Point and Volumetric Imaging, Part 11 JPWL – Wireless) in terms of requirements, typical applications, user interface, protocols and signalling, use of metadata and required algorithms. Each part has been addressed by a common technical management workpackage and by a specific workpackage creating a reference software and appropriate tests and evaluation. It will also add major enhancements to the public JPEG website (www.jpeg.org), with the twin goals of encouraging a European dimension to the site, and allowing it to become self-financed through sponsorship and specific commercial services.

FP5 IST-2001-34144, MOSES, “MPEG Open Security for Embedded Systems” (2002-2004) MOSES expands and enhances multimedia contnet transactions in 3 ways: – standards compliance from OPIMA to emerging areas; – MPEG IPMP Extensions and DVB-CP; – IPMP functionalities in trials to include controlling, copying, moving, exporting and importing protected content in a fully-interconnected environment both peer-to-peer, and in the more classical client server; – supported platforms; – porting legacy secure infrastructures to devices other than PC, e.g. typical CE platforms. MOSES will deliver code as independent of platform and vendor as possible by use of open development suites such as Windows CE and DVB-MHP. This approach, recognising content provider and user needs, and validated in trials will ensure interoperable European content delivery. Objectives: The main objectives of the MOSES project are: 1) extending the OPIMA interfaces and architecture to achieve compliance with the most recent security standards, some of which are still in the making like MPEG IPMP Extensions and DVB-CPCM; 2) extending current business models to encompass operational scenarios where the full set of functionalities pertaining to IPMP systems is implemented and tested, including means for controlling copying, moving, exporting and importing protected content as well as the relevant business and service data; 3) porting this end-to-end MPEG-4 compliant secure infrastructure to devices other than the PC, addressing typical CE platforms based on open development suites, like WinCE and DVB-MHP and point out additional actions needed for subsequent full and successful commercial exploitation. The developed software/hardware aims also at representing a European test-bed where new pieces of technology specified by the main standardisation fora in the field of content protection can be assessed and a co-ordinated European input to standard bodies can be provided.

After myocardial infarction (MI) part of the left ventricle (LV) myocardium is replaced by fibrotic scar tissue and LV regional mechanical properties become regionally different. In the evolution of MI the LV undergoes a remodelling process whereas the remaining functioning myocardium has to undertake the mechanical burden. In this process the LV either effectively compensates for the tissue loss or doesn’t and the LV dilates and clinical heart failure ensues. Current imaging techniques have been applied to the early post-myocardial infarct period, however the geometric analysis they allow don’t predict the future development of remodelling, i.e. some ventricular shapes enlarge while similar ventricles will not. Current approaches either don’t calculate the regional mechanical properties or use simplified geometric assumptions that become grossly inaccurate when there are regional differences (e.g. in ischemic cardiomyopathy).The aim DIE-HEART is to develop a 2D/3D echocardiographic technique (a low cost, non-invasive, non-radiative video technique) able to describe the left ventricle mechanical properties, including the stress/strain relations, the elasticity & mechanical work, applicable in clinical diagnosis & research and animal models. The application of the new methodology will be tested in its ability to detect and calculate the global and regional changes in the LV mechanical properties.

The project has validated the advantages of the new JPEG-2000 standard in the development of critical and real time applications such as medical and remote sensing applications. These applications require efficient implementation of the (de-)compression algorithms for very large images, interactive tools for data selection and personalisation of the content, as well as cooperative discussions and decisions (including diagnostics for the medical applications). OBJECTIVES To promote the use of JPEG-2000 for visual communications in the field of scientific digital images by a specific parametrization of the standard to very large sized images. To demonstrate the scalability and the versatility of the standard by developing an open platform for getting an interactive, secure and multimodal access to very large sized images through IP connections. A two levels architecture has been proposed, one for session management based on session protocols of the IETF and the other for image communications based on JPEG-2000. To develop dedicated tools for setting real-time connections to large image databases. To validate the developed platform and concepts through two user-oriented trials in the field of remote sensing and medical images exchanges.
