CS Colloquium on December 18, 2003 at 2pm Title: Moving morphable models toward photorealism Speaker: Matthew Brand Senior Research Scientist Mitsubishi Electronic Research Labs Cambridge, MA http://www.merl.com/people/brand/ Date: December 18, 2003 (Thursday) Time: 2pm Place: MCS 135, 111 Cummington Street Abstract: Morphable models have been moderately successful in computer vision and highly successful in post-production graphics. The difference is one of economy: An artist in an FX studio will construct a head model with hundreds of morph targets to cover the range of desired deformations for a single character, whereas in computer vision one desires a parsimonious model that gives coverage over a wide range of people and expressions. This is difficult because a morphable model is essentially a linear basis fitted to nature's nonlinear shape (and/or texture) function. I'll survey some more sophisticated approaches to the shape function, the new functionalities they offer, and the technical challenges they present for computer vision.
