An Architecture for TV Content Distributed Search and Retrieval Using the MPEG Query Format (MPQF)

Frédéric Dufaux

Traditional broadcasting of TV contents begins to coexist with new models of user aware content delivery. The definition of interoperable interfaces for precise content search and retrieval between the different involved parties is a requirement for the de ...

Enabling Privacy For Distributed Video Coding by Transform Domain Scrambling

Touradj Ebrahimi, Frédéric Dufaux, Mourad Ouaret

In this paper, a novel scheme for video scrambling is introduced for Distributed Video Coding. The goal is to conceal video information in several applications such as video surveillance and anonymous video communications to preserve privacy. This is achie ...

Error Resiliency of Distributed Video Coding in Wireless Video Communication

Touradj Ebrahimi, Frédéric Dufaux, Mourad Ouaret, Michael Ansorge

Distributed Video Coding (DVC) is a new paradigm in video coding, based on the Slepian-Wolf and Wyner-Ziv theorems. DVC offers a number of potential advantages: flexible partitioning of the complexity between the encoder and decoder, robustness to channel ...

Improved Side Information Generation with Iterative Decoding and Frame Interpolation for Distributed Video Coding

Touradj Ebrahimi, Frédéric Dufaux, Mourad Ouaret

Distributed Video Coding (DVC) is a new paradigm in video coding, which is receiving a lot of interests nowadays. Side Information (SI) generation is a key function in the DVC decoder, and plays a key-role in determining the performance of the codec. This ...

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 ...

Studying Error Resilience Performance for a Feedback Channel Based Transform Domain Wyner-Ziv Video Codec

Touradj Ebrahimi, Frédéric Dufaux

Wyner-Ziv (WZ) video coding is an emerging video coding paradigm based on two major Information Theory results: the Slepian-Wolf and Wyner-Ziv theorems. One of the most interesting and used WZ video coding architectures makes use of a feedback channel (FC) ...

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 ...
