On Comparing Image and Video Compression Algorithms

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 set of High Definition sequences with different spatial resolutions is used for this purpose. Results obtained show quite competitive p ...

Codec-Independent Scalable Distributed Video Coding

Touradj Ebrahimi, Frédéric Dufaux, Mourad Ouaret

In this paper, we introduce novel schemes for scalable Distributed Video Coding (DVC), dealing with temporal, spatial and quality scalabilities. More specifically, conventional coding is used to obtain a base layer. DVC is then applied to generate enhancem ...

A comparative study of JPEG 2000, AVC/H.264, and HD Photo

Touradj Ebrahimi, Francesca De Simone, Frédéric Dufaux, Mourad Ouaret

In this paper, we report a study evaluating rate-distortion performance between JPEG 2000, AVC/H.264 High 4:4:4 Intra and HD Photo. A set of ten high definition color images with different spatial resolutions has been used. Both the PSNR and the perceptual ...

Recent Advances in Multi-view Distributed Video Coding

Touradj Ebrahimi, Frédéric Dufaux, Mourad Ouaret

We consider dense networks of surveillance cameras capturing overlapped images of the same scene from different viewing directions, such a scenario being referred to as multi-view. Data compression is paramount in such a system due to the large amount of c ...

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 ...
