\textbf{Gilles Perrot} is a Ph.D student at the university of Franche-comt\'{e} within the FEMTO-ST Laboratory. His research interests currently focus on GPU-oriented, high performance image processing algorithms. 
His university studies have been conducted at University of Orsay (Paris XI) and at \'{E}cole Normale Sup\'{e}rieure (ENS). 
He received the M.Sc. degree in electrical engineering in 1993.
He received the Agr\'{e}gation of electrical engineering (EE) in 1994 (the highest qualification of teachers in France).
In 1995 he presented a MA thesis in signal processing.
From 1995 to 2009, he has been a EE teacher, technical advisor or manager for several projetcs on Communication and Information technologies.

\textbf{St\'{e}phane Domas} is Assistant Professor at the University of Franche-Comt\'{e}. He is a member of the AND team, within the DISC department of the FEMTO-ST Laboratory. His domain of research is the high performance computing applied to a large range of architectures, from FPGAs and GPUs to widely distributed grid of machines/clusters. More precisely, he is concerned about the development of programming/execution environments for such architectures, and the creation or the optimization of algorithms that take into account their hardware specificities.

\textbf{Rapha\"{e}l Couturier} received the Ph.D. degree in 2000 in Computer Science from the Henri Poincaré
University in Nancy, France. From 2000 to 2006 he was an Assistant Professor in the University of
Franche Comte. Then he has been a Professor in the same University. His research interests include
parallel and distributed algorithms with a strong knowledge on asynchronous iterative methods, and
GPU and FPGA computing. Raphaël authored or co-authored more than 70 papers in conferences
and journals and a book. He has also served in many program committees for conferences.
