This paper presents the EPFL proposal to MPEG-4 video coding standardization activity 1]. The proposed technique is based on a novel approach to audiovisual data compression entitled dynamic coding. The newly born multimedia environment supports a plethora of applications which can not be covered adequately by a single compression technique. Dynamic coding(More)
In this paper, benchmarking results of watermarking techniques are presented. The benchmark includes evaluation of the watermark robustness and the subjective visual image quality. Four different algorithms are compared, and exhaustively tested. One goal of these tests is to evaluate the feasibility of a Common Functional Model (CFM) developed in the(More)
In this paper, we present an overview of the dynamic coding approach, together with recent developments carried out in this framework. Dynamic coding is a general approach to the problem of visual data representation in the context of multimedia. This approach consists in a dynamic combination of multiple representation models and segmentation strategies.(More)
MPEG-4 aims at providing standardized core technologies allowing efficient storage, transmission and manipulation of video data in multimedia environments. In order to achieve this broad goal, rather than a solution for a narrow set of applications, functionalities common to clusters of applications are under consideration. The encoded representation, along(More)
Purpose: The fragmented delivery of health and social services for large groups of patients with chronic conditions was put on the research agenda in 2002 by WHO. The FP7-IHC-project (www.integratedhomecare.eu) aims to develop a turn-key-solution for better clinical continuity to European health regions. Method: The general framework of the project is the(More)
