After two years of engineering school at Phelma, Grenoble-INP, France, I could step into cognitive sciences, especially neurosciences, by an internship at hospital Charité in Berlin, Germany, to work on TEP images in order to forecast diagnosis of Alzheirmer disease with R. Buchert. I finished my studies by a Master of Research in Cognitive Sciences and an internship at LPNC, Grenoble, about infants' color discrimination development with D. Méary and D. Alleysson. By these experiences, I could develop a deep interest in vision science and the mechanisms of visual perception. Joining the image processing team of M. Bertalmío's at the UPF was a great opportunity to merge my scientific profile (see my CV) with a more personnal interest in photography (www.antoinegrimaldi.fr). I'll be in this laboratory for three years in order to achieve my PhD about HDR human-based models and methods for cinema postproduction.
