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 PhD in 2012 and a M.S. degree in 1986, from the ENST-Br with a Dipl.-Ing. degree in 1988.
From 2008 to 2012, I was Lab manager for the Video Processing & Perception research Lab. (36 people, 6 PhD, 2 post-doc, 11 Interns).
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, Content Representation & Coding
With a special focus
on MPEG standards (MPEG-2, MPEG-4 and extensions, HEVC). 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).
Research areas includes also content format representation for new formats (UHD, HDR, 3D,...), new coding schemes and paradigms
(epitome, advanced scenes models), adaptive encoding schemes and perceptual coding.
- Haptic Interfaces for Multimedia Entertainement
We are conducting research on
new interfaces and interactivity to provide the user with new and immersive experiences.
- 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 Content Representation & Coding,
Human Factors (Perception, Vision, Emotion),
Immersive Experience and New Man-Machine Interfaces 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").
