Research in multimedia is always investigating new ways of improving the immersive experience of the users. One current solution consists in designing systems which offer a high level of interactivity, such as multiview content navigation where the point o ...
Dans cet article, nous proposons un nouveau système de codage de vidéo multi-vues, dont la spécificité est de proposer à l’utilisateur une interactivité lui permettant de changer de vue en temps réel. Contrairement aux schémas de codages existant dans la l ...
The Laplacian model is the standard distribution for correlation noise estimation at the turbodecoder in Wyner-Ziv coding schemes. In practice, this hypothesis is not always satisfied and, regularly, the estimated model sensibly differs from the error dist ...
In a multiview-imaging setting, image-acquisition costs could be substantially diminished if some of the cameras operate at a reduced quality. Compressed sensing is proposed to effectuate such a reduction in image quality wherein certain images are acquire ...
Compressed sensing is applied to multiview image sets and inter- image disparity compensation is incorporated into image recon- struction in order to take advantage of the high degree of inter- image correlation common to multiview scenarios. Instead of re ...
Motion estimation (ME) methods based on differential techniques provide useful information for video analysis, and moreover it is relatively easy to embed into them regularity constraints en- forcing for example, contour preservation. On the other hand, th ...
Motion estimation methods based on differential techniques proved to be very useful in the context of video analysis, but have a limited employment in classical video compression because, though accurate, the dense motion vector field they produce requires ...
This paper deals with the side information (SI) generation problem in multiview distributed video coding (MDVC). For inter-view interpolation, we propose a novel dense disparity estimation (DE) approach combined with a popular distributed video coding (DVC ...
Distributed video coding performances strongly depend on the side information quality, built at the decoder. In multi-view schemes, correlations in both time and view directions are exploited, obtaining in general two estimations that need to be merged. Th ...
In the framework of Wyner-Ziv Coding of Video, the coding efficiency depends on the quality of the side information (SI) at the decoder, where the side information is constructed from the key frames available at the decoder. In this paper, we propose a nov ...
