Overview Talk: Geometric representations of 3D scenes

ACM MMSys 2017 will feature a series of overview talks and one of them will be held by Prof. Geraldine Morin from University of Toulouse, France.

Geometric representations of 3D scenes | Geraldine Morin | University of Toulouse, France

Abstract: 3D content is spreading fast as a commonplace media. New technologies like 3D capture devices, head mounted display or 3D printers as well as numerous applications like e-commerce to virtual visits are fostering the use of 3D models. Starting from classical geometric representations limited to dedicated context (CAM-CAD, or game development), adapted models have to be devised in order to meet the constraints imposed by such different application contexts and technologies.

The goal of this talk is to give an overview of the different geometric representations (discrete or continuous, with and without topology) and their advantages and drawbacks. We introduce the existing adaptations of these models for creating, manipulating or sharing these models and their adaptation to specific multimedia applications. In particular, we review 3D compression, 3D model analysis for creation and edition based both on geometry and user interactions, and the different 3D characteristics for indexing 3D models.

Bio:geraldine-morin Géraldine Morin is an Associate Professor at University of Toulouse and a member of the IRIT (Institut de Recherche en Informatique de Toulouse), since 2002. She got her Ph.D. in Computer Science (geometric modeling) from Rice University, Houston, USA and she was a postdoc at the Free University in Berlin, Germany. In January 2014, she defended her habilitation on the use of 3D models as multimedia content. In addition to her recognized work in compact and progressive representation and streaming for 3D plant models (best paper ACM MM 2008), Géraldine Morin worked on image based representations. More recently, she worked on identifying similarities in a 3D model and 3D applications indexing. In addition, she participated in work on the analysis of user interactions to adapt 3D content and their interactions. She is currently interested in using skeletons for shape analysis and image based reconstruction. Géraldine Morin served a member of SIAM-Geometric Design Group office, she is an associate member of the French-Singaporean lab IPAL and she is co-head of the French Geometric Modeling Group; she participated in the program committee of several national and international conferences. She published 14 papers in international journals and 36 in international conferences and workshops, and co-advised 7 graduated Ph.D. students and is currently directing two.
