Lossy to lossless object-based coding of 3-D MRI data

Jean-Philippe Thiran, Gloria Menegaz

We propose a fully three-dimensional object-based coding system exploiting the diagnostic relevance of the different regions of the volumetric data for rate allocation. The data are first decorrelated via a 3D discrete wavelet transform. The implementation ...

An ASIC implementation of adaptive arithmetic coding

Andreas Peter Burg

In this work, we present an improved version of an ASIC implementation of the adaptive arithmetic coding algorithm which uses a two-level memory hierarchy. We propose algorithmic modifications and a special hardware structure to speed-up the design without ...

Broadcast quality video over IP

We consider the problem of designing systems for the transmission of high-quality video signals over certain high-speed segments of the public IP network. Our most important contribution is the definition of a network/coder interface for IP networks which ...

Joint Source/FEC Rate Selection for Quality-Optimal MPEG-2 Video Delivery

Pascal Frossard

This paper deals with the optimal allocation of MPEG-2 encoding and media-independent Forward Error Correction (FEC) rates under a total given bandwidth. The optimality is defined in terms of minimum perceptual end-to-end distortion given a set of video an ...

Text Identification in Complex Background using SVM

Jean-Philippe Thiran, Hervé Bourlard, Datong Chen

This paper presents a fast and robust algorithm to identify text in image or video frames with complex backgrounds and compression effects. The algorithm first extracts the candidate text line on the basis of edge analysis, baseline location and heuristic ...

On optimal low-complexity source/channel coding

Martin Vetterli, Michael Christoph Gastpar, Bixio Rimoldi

Shannon's separation theorem gives a conceptually and practically appealing way to construct an optimal communication system in two independent steps, namely source compression and channel coding. However, sometimes it is worth considering {\em joint} sour ...

Joint Source/FEC Rate Selection for Optimal MPEG-2 Video Delivery

Pascal Frossard

This paper deals with the optimal allocation of MPEG-2 encoding and media-independent FEC rates under a total given bandwidth. The optimality is defined in terms of minimum perceptual end-to-end distortion given a set of video and network parameters. We fi ...

User-Oriented QoS Analysis in MPEG-2 Video Delivery

Pascal Frossard

We address the problem of video quality prediction and control for high-resolution video transmitted over lossy packet networks. In packet video, the bitstream flows through several subsystems (coder, network, decoder); each of them can impair the informat ...

Designing new network adaptation and ATM adaptation layers for interactive multimedia applications

Multimedia services, audiovisual applications composed of a combination of discrete and continuous data streams, will be a major part of the traffic flowing in the next generation of high speed networks. The cornerstones for multimedia are Asynchronous Tra ...
