Symmetry Detection and Structure Discovery for Digital 3D Geometry

With recent advances in 3D acquisition technology we witness a 
tremendous growth in the size and complexity of digital 3D models at all 
scales. We are now capable of digitizing entire cities, reconstruct the 
intricate 3D structures of human organs, or build accurate spatial 
representations of complex molecules. One of the key challenges in 
processing such data is finding and extracting geometric content 
relevant for a specific application.
In this talk I will introduce a computational framework for symmetry 
detection and structure discovery in digital 3D geometry. The approach 
is fully automatic and assumes no prior knowledge on the location, size, 
or shape of the symmetric elements. Based on a statistical analysis of 
pairwise similarity transformations, our method successfully discovers 
complex regular structures amidst clutter, noise, and missing geometry. 
This enables applications in model repair, automated data 
classification, shape retrieval, reverse engineering, or compression.
I will also discuss how symmetry detection and geometric optimization 
methods can be combined to yield an effective tool for shape design that 
allows enhancing or de-emphasising symmetries.

Mark Pauly is an assistant professor at the CS department of ETH Zurich. 
>From August 2003 to March 2005 he was a postdoctoral scholar at Stanford 
University, where he also held a position as visiting assistant 
professor during the summer of 2005. He received his Ph.D. degree (with 
distinction) in 2003 from ETH Zurich and his M.S. degree (with honors) 
in 1999 from TU Kaiserslautern. His research interests include computer 
graphics and animation, geometry processing, shape modeling and 
analysis, and computational geometry. He was recipient of a full-time 
scholarship of the German National Merit Foundation, received the ETH 
medal for outstanding dissertation, and was awarded the Eurographics 
Young Researcher Award in 2006.
