For the weekly seminar of the STORM research group, Romain Vergne from the Université of Grenoble Alpes will give a talk on Ensuring congruency between light & shape.

This seminar will take place this week on Wednesday 16/01 at 13:00pm in the Salle des Thèses at IRIT. The presentation will be in french.

Abstract
This talk will be decomposed into 2 parts: first, I will first present an overview of recent previous works that cover most of my research interests (texture synthesis, image edition and expressive rendering). Next, I will focus more particularly on an ongoing project related to the perception and exaggeration of shape in a 3D rendering context. The goal of this project is to locally modify the direction of the light at multiple scales to ensure a proper congruency with shape features, and consequently to better depict shape in rendered images

Bio
Romain Vergne is associate professor at the University of Grenoble Alpes (France) and researcher in the Maverick team (Inria, LJK) since 2012. The main goal of his research is to (1) study the phenomenological links between shapes, light and matter in order to (2) design perceptually plausible computer graphics tools to edit the appearance of objects in computer generated images and photographs. Previously, he was a post-doc researcher at the Justus Liebig University of Giessen (Germany). He studied color constancy with Karl R. Gegenfurtner and shape perception with Roland W. Fleming in 2011 and 2012. He defended his Ph.D. in computer graphics in 2010 at the University of Bordeaux under the supervision of Christophe Schlick, Xavier Granier and Pascal Barla.
