Everything in the physical world can be deconstructed into three-dimensional geometry. Recent technological advances in sensing devices have allowed us to easily obtain a sparse, low-fidelity and incomplete digital representation of our world. Mere acquisition, however, is insufficient; we can achieve the 3D sensing revolution only through the development of algorithms capable of processing corrupted geometric data. This is essential for the creation of effective means of interaction for both real and virtual environments. Enhanced understanding of digital geometry will allow better automated control for robotics and engineering, highly effective virtual training, as well as truly immersive gaming experiences. In this talk, I will cover my efforts in this domain, and discuss techniques in both static and dynamic geometry analysis. I will start by covering my research in static analysis, presenting techniques for the computation of correspondences between shapes, identification of symmetries and extraction of shape skeletons. I will then shift toward the processing of dynamic geometry, presenting very recent results on robust registration, real-time hand tracking as well as digital facial avatar creation.


Andrea Tagliasacchi is a postdoctoral researcher in the Graphics and Geometry Laboratory at EPFL (Switzerland). Prior to joining EPFL, Andrea obtained his M.Sc. (cum laude, gold medal in ENCS) with a focus on digital signal processing from Politecnico di Milano (Italy). He completed his Ph.D. in 2013 at Simon Fraser University as an NSERC Alexander Graham Bell scholar. His doctoral research at SFU focused on digital geometry processing. He also worked at Electronic Arts on the early developments of the Kinect sensor, and was a research visitor at INRIA (France) on robust geometry processing.
