The Weizmann Institute of Science Faculty of Mathematics and Computer Science Vision and Robotics Seminar Seminar Room, Room 261, Ziskind Building on Monday, January 31, 2011 13:00 - 14:00 Note unusual day/time/location Greg Shakhnarovich Toyota Technological Institute at Chicago will speak on Detection of 3D primitives in a single image Abstract: 3D primitives are objects whose shape is described by a rigid geometric configuration of solid faces, parameterized only by anisotropic scaling. I will describe ongoing work towards simultaneous detection, pose estimation, and recovery of relative scaling of such primitives from a single image. Our approach relies on a graphical model that represents the primitive class. The model captures constraints imposed by the model, and uses an efficient implementation of approximate inference to select a subset of image features consistent with a detection hypothesis. We combine this idea with a novel method for pose estimation, that uses example-based inference jointly with more traditional approaches. The resulting system is capable of detecting objects in the presence of clutter, occlusions, and noise. Joint work with Payman Yadollahpour. --------------------------------------------------------- Technion Math Net-2 (TECHMATH2) Editor: Michael Cwikel <techm@math.technion.ac.il> Announcement from: Diana Mandelik <diana.mandelik@weizmann.ac.il>
