We want to redisplay captured video data to reveal aspects of the world that we otherwise don't see. I'll present three examples in this theme. (1) Motion without movement can capture, then redisplay, instantaneous visual motion. (2) Shapetime photography shows the relationship between moving shapes at different times. (3) Motion microscopy analyzes small motions, then re-renders the video with selected motions amplified. These projects are joint work with: Ted Adelson, Fredo Durand, David Heeger, Ce Liu, Antonio Torralba, and Hao Zhang.


Speaker Biography

Dr. William Freeman worked at Mitsubishi Electric Research Labs (MERL), in Cambridge, MA, most recently as Sr. Research Scientist and Associate Director from 1992 - 2001. He studied computer vision for his PhD in 1992 from the Massachussetts Institute of Technology, and received a BS in physics and MS in electrical engineering from Stanford in 1979, and an MS in applied physics from Cornell in 1981.

His current research interests include machine learning applied to computer vision, Bayesian models of visual perception, and interactive applications of computer vision. In 1997, he received the Outstanding Paper prize at the Conference on Computer Vision and Pattern Recognition for work on applying bilinear models to "separating style and content". Previous research topics include steerable filters and pyramids, the generic viewpoint assumption, color constancy, and computer vision for computer games. He holds 25 patents.

From 1981 - 1987, he worked at the Polaroid Corporation . There he co-developed an electronic printer (Polaroid Palette) , and developed algorithms for color image reconstruction which are used in Polaroid's electronic camera . In 1987-88, Dr. Freeman was a Foreign Expert at the Taiyuan University of Technology , P. R. of China.

Dr. Freeman was an Associate Editor of IEEE Trans. on Pattern Analysis and Machine Intelligence (IEEE-PAMI), and is a member of the IEEE PAMI TC Awards Committee. He is active in the program or organizing committees of the International Conference on Face and Gesture Recognition, Computer Vision and Pattern Recognition (CVPR), the International Conference on Computer Vision (ICCV), Neural Information Processing Systems (NIPS), and SIGGRAPH. He is the program co-chair for ICCV 2005.
