Senior Scientist

Imaging Science Lab Researchers

I am a senior scientist at Technicolor Research & Innovation France. I studied Physics and Signal Processing at the University. In 1995, I received an academic Master’s degree from Rennes University and one year later a post master’s degree from the ENST Bretagne French engineering school. In 1996, I joined Thomson/Technicolor as a R&D Engineer and started to work on camera and front projection display materials. Rapidly, I focused on picture quality improvement for displays. I have developed several algorithms; some of them are based on motion estimation and compensation techniques, they are implemented in several professional products (video encoder MPEG2/4 HD and SD), frame rate converter, video de-interlacing for Mobile TV platform). From 2003 to 2009, I worked on Plasma Display Panel Picture quality subject in co-operation with a Korean Company and managed Rennes Plasma team. From 2009 to present, I have been involved in Software algorithm research for film restoration topic and semi-automatic or automatic software tool for professional video post production.

Research interests:

My main research area covers picture quality enhancement,spatio-temporal effects in video sequence, motion estimation/compensation, flat panel display addressing and technologies.

For the last two years, I have been working on color mapping and High Dynamic Range (HDR) video topics


I am involved in color mapping project for professional video post production and in HDR topic, particularly on reverse tone mapping algorithm development

List of achievements:

Transfers to Business Units/ Customers:

  • Color plane registration module for film restoration developed and integrated in a Technicolor restoration tool (2011)
  • Real time motion estimation/compensation 50 inches plasma prototype upgraded and transferred (from 2003 to 2009)
  • Real time deinterlacing algorithm was implemented on PC platform and is used in a Mobile TV platform for mobile phone application (2008)
  • A high definition version of a HD_motion estimator (2005) was integrated in a MPEG2/4 encoder product.
  • SD video motion estimator (2001), this IP block is used in the pre processing module of a professional video encoder product.
