Google Tech Talks February, 29 2008 ABSTRACT I will present recent work for acquiring, rendering, and displaying photoreal models of people, objects, and dynamic performances. I will overview image-based lighting techniques for photorealistic compositing and reflectance acquisition techniques which have been used to create realistic digital actors in films such as "Spider Man 2" and "Superman Returns". I will then describe initial work with our lab's Light Stage 6 system to combine image-based relighting with free-viewpoint video to capture and render full-body performances. I will also describe a new 3D face scanning process that captures high-resolution skin detail by estimating surface orientation from the skin's reflection of polarized spherical gradient illumination. I will conclude by describing a new 3D display that leverages 5000 frames per second video projection to show autostereoscopic, interactive 3D imagery to any number of viewers simultaneously. Speaker: Dr. Paul Debevec, University of Southern California Institute for Creative Technologies Paul Debevec is the associate director of graphics research at USC's Institute for Creative Technologies (USC ICT) and a research associate professor at USC's Department of Computer Science. His Ph.D. thesis at UC Berkeley presented Façade, an image-based modeling and rendering system for creating photoreal virtual camera motion through architectural scenes from photographs. Using Façade he led the creation of a ...
