Multiview Distributed Video Coding with Encoder Driven Fusion

Touradj Ebrahimi, Frédéric Dufaux, Mourad Ouaret

In this paper, a scheme based on multiview and Distributed Video Coding (DVC) is introduced. More specifically, a new fusion technique between temporal, homography and Disparity Compensation View Prediction (DCVP) side informations is introduced. For this ...

Multiple Description H.264 Coding with Redundant Pictures

Pascal Frossard, Ivana Radulovic

Multiple description coding (MDC) o®ers a competitive so- lution for video transmission over lossy packet networks, with a graceful degradation of the reproduced quality as the loss rate increases. This paper illustrates how redundant pictures, an error re ...

Low delay video coding

Analogue wireless cameras have been employed for decades, however they have not become an universal solution due to their difficulties of set up and use. The main problem is the link robustness which mainly depends on the requirement of a line-of-sight vie ...

Flexible Motion-Adaptive Video Coding with Redundant Expansions

Pascal Frossard, Pierre Vandergheynst, Adel Rahmoune

This paper presents a highly flexible video coding scheme (MP3D), based on the use of a redundant 3-D spatio-temporal dictionary of functions. Directionality and anisotropic scaling are key ingredients to the spatial components, that form a rich collection ...

Low rate and flexible image coding with redundant representations

Pascal Frossard, Pierre Vandergheynst

New breakthroughs in image coding possibly rely in signal decomposition through non-separable basis functions. The work proposed in this paper provides an adaptive way of representing images as a sum of two-dimensional features. It presents a low bit-rate ...

JPEG2000 image coding system theory and applications

Touradj Ebrahimi

JPEG2000, the new standard for still image coding, provides a new framework and an integrated toolbox to better address increasing needs for compression. It offers a wide range of functionalities such as lossless and lossy coding, embedded lossy to lossles ...

Unbalanced Quantized Multi-State Video Coding

Pascal Frossard

Multi-State Video Coding (MSVC) is a multiple description scheme based on frame-wise splitting of the video sequence into two or more subsequences. Each subsequence is encoded separately to generate descriptions which can be decoded independently. Due to s ...

On Evaluating Video Object Segmentation Quality: A Perceptually driven Objective Metric

Touradj Ebrahimi, Elisa Drelie Gelasca

Segmentation of moving objects in image sequences plays an important role in video processing and analysis. Evaluating the quality of segmentation results is necessary to allow the appropriate selection of segmentation algorithms and to tune their paramete ...

On Comparing JPEG 2000 and Intraframe AVC

Touradj Ebrahimi, Frédéric Dufaux, Mourad Ouaret

In this work, a performance evaluation of AVC Intra and JPEG2000 in terms of rate-distortion performance is conducted. A rich set of test sequences with different spatial resolutions is used in this evaluation. Furthermore, the comparison is made with both ...
