タイトル: Photometric 3-D Modeling
Over the past two decades, we have seen tremendous theoretical advances in photometric methods for 3-D modeling, where we wish to reconstruct the scene geometry from observed images under varying lighting conditions. These advances now motivate us to more practical applications in industry, or even in our daily life. This talk introduces recent advances in photometric 3-D modeling, especially in the aspect of generalization of the photometric stereo method. More specifically, we introduce a couple of recent techniques to remove restricting assumptions (e.g., Lambertian surface) for making photometric stereo to work in more general conditions.
Yasuyuki Matsushita received his B.S., M.S. and Ph.D. degrees in EECS from the University of Tokyo in 1998, 2000, and 2003, respectively. He joined Microsoft Research Asia in April 2003. He is a Lead Researcher in Visual Computing Group. His areas of research are computer vision (photometric techniques, such as radiometric calibration, photometric stereo, shape-from-shading), computer graphics (image relighting, video analysis and synthesis). Dr. Matsushita served as an Area Chair for IEEE Computer Vision and Pattern Recognition (CVPR) 2009 and International Conference on Computer Vision (ICCV) 2009, and he is on the editorial board member of International Journal of Computer Vision (IJCV), IPSJ Journal of Computer Vision and Applications (CVA), The Visual Computer Journal, and Encyclopedia of Computer Vision. He serves as a Program Co-Chair of PSIVT 2010, 3DIMPVT 2011, ACCV 2012, Demo Co-Chair for ICCV 2011. From April 2010, he is appointed as a Guest Associate Professor at Osaka University, Japan. He is a member of IEEE.
