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 ...

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 ...

Hybrid video coding using bi-dimensional matching pursuit

Pierre Vandergheynst, Lorenzo Granai, Lorenzo Peotta, Emilio Maggio

In this report we propose a new coding scheme based on the Matching Pursuit algorithm and exploiting some of the new features introduced by H.264 for motion estimation. Main points of this work are the design of a redundant dictionary suitable for coding d ...

Modeling of 2D+1 texture movies for video coding

Julien Reichel, Gloria Menegaz

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 ...

Video multicast over fair queueing networks

Martin Vetterli

We consider the problem of video multicast over networks that enforce fair bandwidth allocations in the routers. State-of-the-art layered IP multicast systems perform well for moderately sized sessions, but suffer from three basic problems that prevent the ...

Noise Reduction Techniques for Video Coding Applications

Luciano Sbaiz

Granular noise is visually bothersome with respect to high quality rendition, and it is a well known source of visual artifacts for coding algorithms. This work considers the application of nonlinear filtering techniques to granular noise reduction and the ...

Video Transport in ATM Networks

Video applications are expected to generate a significant proportion of the traffic in the future B-ISDN. We consider the different possibilities for the transport of video signals provided by the service classes defined by the ATM Forum and the ITU-T, foc ...

Quality Assessment of Image Features in Video Coding

Olivier Verscheure

This paper describes an extension of a vision model for video that has been designed to estimate how specific features in moving pictures are rendered as a consequence of a compression process. The resulting model permits to evaluate the distortions on con ...

Perceptual Quality Measure using a Spatio-Temporal Model of the Human Visual System

Olivier Verscheure

This paper addresses the problem of quality estimation of digitally coded video sequences. The topic is of great interest since many products in digital video are about to be released and it is thus important to have robust methodologies for testing and pe ...

Statistical Based Motion Estimation for Video Coding

Luciano Sbaiz

In this work, statistical based motion estimation is applied to the problem of motion estimation for video coding. We show that the motion equations of a rigid body can be formulated as a nonlinear dynamic system whose state is represented by the motion pa ...
