Dear colleagues and students, On Friday 23.06, Silvia Sellán from the Dynamic Graphics Project at the University of Toronto will be visiting us to hold a talk about her recent cutting-edge research on stochastic surface reconstruction for recovering shapes from 3D point clouds. Silvia has a proven track record of publishing innovative research at the top venues of her field, and we in the Computer Animation group are thrilled to have her visit. Details below! */When/*: Friday 23.06, 14:00-15:00. */Where/*: Seminar Room 118, Building E3, Floor 1 Mies-van-der-Rohe-Straße, 52074 Aachen (same floor as the Computer Graphics group) /*Title*/: Uncertain Surface Reconstruction */Abstract/*: We propose a method to introduce uncertainty to the surface reconstruction problem. Specifically, we introduce a statistical extension of the classic Poisson Surface Reconstruction algorithm for recovering shapes from 3D point clouds. Instead of outputting an implicit function, we represent the reconstructed shape as a modified Gaussian Process, which allows us to conduct statistical queries (e.g., the likelihood of a point in space being on the surface or inside a solid). We show that this perspective improves PSR's integration into the online scanning process, broadens its application realm, and opens the door to other lines of research such as applying task-specific priors. /*Bio*/: Silvia is a fourth year Computer Science PhD student at the University of Toronto. She is advised by Alec Jacobson and working in Computer Graphics and Geometry Processing. She is a Vanier Doctoral Scholar, an Adobe Research Fellow and the winner of the 2021 University of Toronto Arts & Science Dean’s Doctoral Excellence Scholarship. She has interned twice at Adobe Research and twice at the Fields Institute of Mathematics. She is also a founder and organizer of the Toronto Geometry Colloquium and a member of WiGRAPH. She is currently looking to survey potential future postdoc and faculty positions, starting Fall 2024. Looking forward to seeing curious researchers and students alike next Friday! Sincerely, Andreas Longva, Msc. Computer Animation group Visual Computing Institute
