Summary
Since 1989 I am working with Technicolor Research & Innovation (Formely Thomson Research). I am currently part of the Rennes Lab, France focusing on Video Compression (2D and 3D) and Human Perception technologies. I am graduated from the University of Rennes I with a M.S. 1 degree in 1986, and from the ENST-Br with a Dipl.-Ing. degree in 1988.
Since 2008, I am Lab manager for the Video Processing & Perception research Lab.
Since 2010, I am distinguished Scientist at Technicolor Research and Innovation - Video Perception, Processing & Coding.

Past & Current Works
I have worked for Technicolor Research Labs in the following areas:

- Research on Video processing & Coding algorithms, with a special focus on MPEG standards (MPEG-2, MPEG-4 and extensions). I have contributed to the specification and development of our business divisions products such as real-time video encoders, taking into account implementation constraints (hardware, software and IC). Those encoders have been recognized as worlwide most efficient broadcast encoders (with several awards).
- Human vision modeling and especially saliency map computation, subjective video quality metrics and re-framing applications. The Technicolor saliency computation model is published in several journal papers.

More on this topic can be found here.

- Video Streaming over Internet and other distribution systems (based on MPEG-2 TS and IP protocols). I have been active in the writing of the DVB specification for the deploiement of the Digital Terrestrial Television in Europe. I have studied adaptive video streaming over IP networks in 1998-2000, using scalable video coding approaches and modified RTP protocols.
- Digital modulation & error protection for robust delivery of video. I made some work in this area that lead to the development of joint source channel coding schemes.
- Focusing now on next generation video formats (2D, 3D, HDR, 4k...) and standards to improve the user experience.

During these years, I have been in charge of several research projects and teams (4 to 6 people), including also relationship with our business division, but also academics and industrial research labs through collaborative projects and interns (PhD, master ...).

I have also been involved in several European & French collaborative projects such as EUREKA95 (HDMAC), RACE dTTb (digital transmissions), ACTS HAMLET (MPEG2), ESPRIT/ROXY (Internet multicast), IST/Ozone (Ambient Intelligence), ITEA/HD4U (HDTV digital TV). Being Project leader for the RNRT/VISI (video over IP) project, and workpackage leader of the most recent FUI/FuturIm@ges (Future Image formats, 2D/3D) project.

I was also member of a number of standards organizations such as MPEG, AFNOR, DVB and some groups (GdR-ISIS, Pôle de compétitivité "images & réseaux").
