The M-Term Pursuit for Image Representation and Progressive Compression

Pascal Frossard, Pierre Vandergheynst, Adel Rahmoune

This paper introduces a sparse signal representation algorithm in redundant dictionaries, called the M-Term Pursuit (MTP), with an application to image representation and scalable coding. The MTP algorithm belongs to the framework of the matching pursuit ( ...

Playback Delay Optimization in Scalable Video Streaming

Pascal Frossard, Jean-Paul Wagner

This paper addresses the problem of optimizing the playback delay experienced by a population of heterogeneous clients, in video streaming applications. We consider a typical broadcast scenario, where clients subscribe to different portions of a scalable v ...

MPEG-7 Description for Scalable Video Reconstruction

Touradj Ebrahimi

We present an MPEG--7 compliant description of video sequences for scalable transmission and reconstruction. The proposed method is content-based and permits efficient and flexible video coding while keeping the benefits of textual descriptions in database ...

Parametric coding of spatial audio

Christof Faller

A wide range of techniques for coding a single speech or audio signal channel have been developed over the last few decades. In addition to pure redundancy reduction, sophisticated source and receiver models have been considered for reducing the bitrate. O ...

Color image scalable coding with Matching Pursuit

Pascal Frossard, Pierre Vandergheynst

This paper presents a new scalable and highly flexible color image coder based on a Matching Pursuit expansion. The Matching Pursuit algorithm provides an intrinsically progressive stream and the proposed coder allows us to reconstruct color information fr ...

Scalable Motion-Adaptive Video Coding with Redundant Representations

Pascal Frossard, Pierre Vandergheynst, Adel Rahmoune

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 ...

Augmented CGI Films

Daniel Thalmann, Frédéric Vexo

The contribution of this paper focuses on the definition of a multimedia application targeted at turning CGI films into a richer and more interactive experience. We combine highquality animated graphics to present a compelling story and enrich it by introd ...

Adaptive video streaming in lossy networks: versions or layers?

Pascal Frossard, Ivana Radulovic

This paper tackles low delay adaptive video streaming over error-prone networks. Our framework consists of an encoding station, an edge server and a set of clients with various access rates. The edge server is capable of performing simple error concealment ...

A flexible framework for efficient design of advanced 3D audio systems in multimedia applications

Aleksandar Simeonov

The recent advance of computer technology pushed the computing power of the modern computer systems to unprecedented levels; modern processors moved from the conventional, scalar type of architecture to more sophisticated, parallel ones, combining fast pro ...

On Compression Using the Distributed Karhunen-Loeve Transform

Martin Vetterli, Michael Christoph Gastpar, Pier Luigi Dragotti

In this paper, we discuss a framework for the distributed compression of vector sources, based on our previous work on distributed transform coding. In particular, our goal is to develop a strategy of first applying a suitable distributed Karhunen-Loeve tr ...
