This paper describes a novel video coding scheme based on a three-dimensional Matching Pursuit algorithm. In addition to good compression performance at low bit rate, the proposed coder allows for flexible spatial, temporal and rate scalability thanks to i ...
We propose a novel model-based coding system for video. Model-based coding aims at improving compression gain by replacing the non-informative image elements with some perceptually equivalent models. Images enclosing large textured regions are ideal candid ...
Currently, portable consumer embedded devices are increasing more and more their capabilities and can now implement new algorithms (e.g. multimedia and wireless protocols) that a few years ago were resewed only for powerful workstations. Unfortunately, the ...
This paper presents a scalable video coding scheme (MP3D), based on the use of a redundant 3-D spatio-temporal dictionary of functions. The spatial component of the dictionary consists of directional and anisotropically scaled functions, which form a rich ...
Two groups of 10 Parkinson’s disease (PD) patients and 10 age-matched Normal subjects performing normal life activities were recorded using a portable recorder and 3D gyroscopes. PD patients had sub-thalamic stimulation implantation for 20±3 months. The PD ...
We present an automatic content-based video transcoding algorithm which is based on how humans perceive visual information. The transcoder support multiple video objects and their description. First the video is decomposed into meaningful objects through s ...
A growing and important class of traffic in the Internet is so-called `streaming media,' in which a server transmits a packetized multimedia signal to a receiver that buffers the packets for playback. This playback buffer, if adequately sized, counteracts ...
This paper presents a novel, MPEG-4 compliant animation engine (body player). It has been designed to synthesize virtual human full-body animations in interactive multimedia applications for the web. We believe that a full-body player can provide a more ex ...
We propose a new, highly flexible font description method that explicitly describes characters as assemblies of parameterizable shape components. By varying global parameters, we can derive fonts that vary in weight, condensation, and shape. Fonts made of ...
Peer-To-Peer systems are driving a major paradigm shift in the era of genuinely distributed computing. Gnutella is a good exam- ple of a Peer-To-Peer success story: a rather simple software enables Internet users to freely exchange files, such as MP3 music ...
