   Research activities

2014-Today

Research engineer  UMS IRMaGe, Unité IRM 3T Recherche, Teaching Hospital of Grenoble, France

Participation to French project ERATRANIRMA (ANR funding): medial imaging via MRI. Design and development of spatial encoding tools for MRI, with the objective of providing a fast and real-time image reconstruction chain.

Collaboration with Laurent Lamalle

2012–2014

Post-doctoral  Institut de Recherche en Communications et Cybernétique de Nantes (IRCCyN), Nantes, France

Participation to French project StreamMaster (OSEO funding), study of a still image watermarking algorithm robust to print & scan. Focus on the invisibility of the watermark (psychophysics) and optimization of the detection (statistics). Design and implementation (C++) of the technology; validation by subjective experiments. The proposed implementation has been integrated within a partner’s industrial process.

Collaboration with Florent Autrusseau and Dalila Goudia

2011–2012

Post-doctoral  IRCCyN, Nantes, France

Active participation to european ITEA 2 project JEDI, focus on visual fatigue and visual confort of 3D stereoscopic contents and displays, organization of subjective experiments campaigns, study and set-up of a non-standardized subjective test room, shooting of 3D stereoscopic contents, electrophysiological measurements (EEG, EMG, EOG).

Collaboration with Patrick Le Callet and Marcus Barkowsky

2007–2011

Industrial PhD  Orange Labs (France Télécom R&D) + Institut d’Electronique et de Télécommunications de Rennes (IETR), Rennes, France

Worked on a disruptive approach to video representation and compression. From a spatio-temporal video unit called “motion tubes”, I aimed at improving both the compression efficiency and the representation functionalities.

Supervised by Stéphane Pateux and Nathalie Cammas (both research engineers at France Télécom R&D, Rennes, France)

2006–2007

Final year project  University of Strathclyde, Glasgow, Scotland

Designed and implemented a video object tracking algorithm in Matlab. Application to the tracking of vehicles.

Project supervised by John Soraghan, Centre for Excellence in Signal & Image Processing (CeSIP)

Summer 2006

Internship in an Academic lab  IETR, Rennes, France

Designed and implemented (in C) a robust entropy coding algorithm for a still-image coding scheme.

Project carried out within team LAR, led by Olivier Déforges and Marie Babel, under the management of Joseph Ronsin.
