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 ...

Perceptual Blur and Ringing Metrics: Application to JPEG2000

Touradj Ebrahimi

In this paper, we present full-reference as well as no-reference metrics for typical JPEG 2000 compression artifacts, namely blur and ringing. These metrics are based on an analysis of the edges and adjacent regions in an image. Their perceptual significan ...

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 ...

Method for marking a compressed digital video signal

Touradj Ebrahimi, Frédéric Jordan

A method for marking a compressed digital video signal by embedding a digital signature in the compressed video signal, the signal representing a series of at least two video images, each image being divided into a plurality of regions, the signal includin ...

Image security and processing in the JPEG 2000 compressed domain

Raphaël Grosbois

Digital images are becoming increasingly successful thanks to the development and the facilitated access to systems permitting their generation (i.e. camera, scanner, imaging software, etc). A digital image basically corresponds to a 2D discrete set of reg ...

Video Coding with Lifted Wavelet Transforms and Frame-Adaptive Motion Compensation

This paper investigates video coding with wavelet transforms applied in the temporal direction of a video sequence. The wavelets are implemented with the lifting scheme in order to permit motion compensation between successive pictures. We generalize the c ...

Motion JPEG 2000 for Wireless Applications

Touradj Ebrahimi

In this paper, we analyze the performance of Motion JPEG2000 for wireless applications. This new standard is based on intra-frame wavelet coding. Motion JPEG2000 is offering a number of very compelling advantages when compared to state-of-the-art MPEG-4 vi ...

High flexibility scalable image coding

Pascal Frossard, Pierre Vandergheynst

This paper presents a new, highly flexible, scalable image coder based on a Matching Pursuit expansion. The dictionary of atoms is built by translation, rotation and anisotropic refinement of gaussian functions, in order to efficiently capture edges in nat ...

Video Coding Using a Deformation Compensation Algorithm Based on Adaptive Matching Pursuit Image Decompositions

Pierre Vandergheynst, Oscar Divorra Escoda

Today's video codecs employ motion compensated prediction in combination with block matching techniques. These techniques, although achieving some level of adaptivity in their latest versions, continue to rely on the decomposition of frames on a set of art ...

Video quality evaluation for mobile applications

Frédéric Dufaux, Stefan Winkler

This paper presents the results of our quality evaluations of video sequences encoded for and transmitted over a wireless channel. We selected content, codecs, bitrates and bit error patterns representative of mobile applications and we concentrated on the ...
