Profile

In 2001 I received the Engineer Degree in Electric Energy and Information Sciences from the Ecole Supérieure d'Electricité (Supélec), together with a Master Degree in Signal Processing from the Rennes-1 University. Then I've pursued a Ph.D. thesis on scalable video compression, as a CIFRE convention between IRISA and Thomson R&D - till late 2004. Christine Guillemot was my supervisor. I defended my thesis in the very beginning of 2005, and have been working so far as a research engineer in Thomson's "Video Compression" research lab.

Research Activities

Scalable Video Compression

My Ph.D. thesis is entitled "Highly scalable descriptions for video compression over wide resolutions/bit-rates range". That work was dedicated to media streaming/casting over heterogeneous networks. The goal was to deliver an embedded bit-stream that could be decoded at various resoutions and bit-rates (from SDTV 6Mbps to QCIF 64Kbps), without lowering compression efficiency in comparison with state-of-the-art non-scalable approaches. Among many topics, I investigated the fields of wavelet transforms, contextual entropic (arithmetic) coding, motion estimation and coding, motion-compensated temporal filtering and muti-resolution analysis. If interested, see my defense slides (in french...).
At that time, in the framework of my thesis, Thomson and IRISA collaborated to submit a common contribution, named TWAVIX (for Thomson Wavelet-based Scalable Coding Scheme), to the MPEG's Call for Proposals on Scalable Video Coding. Since, unfortunately - as one may know -, MPEG and the ITU recently dropped off from the upcoming SVC standard the very last vestige of wavelets...

And besides...

In Thomson I've been going on working on the same topics so far, promoting in addition JPEG2000 in Thomson's Business Units (Cameras, Digital Cinema Post-production system, Technicolor) and supporting them to acquire a sufficient knowledge of the standard.
Meanwhile, I recently got with great interest too into directional (so-called "geometric" or "oriented") wavelets and distributed coding.
