Talk by Professor Ruigang Yang, Department of Computer Science, University of Kentucky
Time: May 11, 1pm Place: Rm.2311 (CS Wireless Seminar Room), Computer Science Building

Digital Photograph and video are now ubiquitous in our everyday life. However, they capture only a 2D projection of our 3D world. The central theme of my research is how to effectively acquire and visualize objects in 3D. In this talk, I will present several approaches for 3D modeling, from real-time automatic reconstruction of static scenes to stitching partial height maps to a complete space-time model. In particular, I will present a new method that combines 3D reconstruction with physically-based simulation. This marriage is mutually beneficial: physically-based simulation can help identify outliers in 3D reconstruction and fill in the missing part in a plausible way; and 3D information from reconstruction removes the needs to manually set up simulation parameters. Applying this principle to dynamic fluid modeling shows that visually pleasing results can be obtained from as few as one pair of video cameras. Since all of these techniques require only a single video or depth augmented video stream as input, We envision that they could be adopted in the future to allow everyone to capture and re-experience real-world events in interactive 3D.

Some of the work is in collaboration with Huamin Wang and Greg Turk at Georgia Tech and Marc Pollefeys et al. at UNC-Chapel Hill.
