Abstract

The level set method for capturing moving fronts was introduced in 1987 by Osher and Sethian. It has proven to be phenomenally successful as a numerical device. For example, typing in "Level Set Methods" on Google's search engine gives roughly 3200 responses. Applications range from capturing multiphase fluid dynamical flows to special effects in Hollywood to visualization, image processing, control, epitaxial growth, computer vision and many more. In this talk we shall give an overview of the numerical technology and a few graphics oriented applications.

About the Speaker

Stan Osher is Professor of Mathematics and Director of Applied Mathematics at University of California, Los Angeles. He is the coinventor and a principle developer of widely used state-of-the-art high resolution schemes for approximating hyperbolic conservation laws and Hamilton-Jacobi equations; level set methods for computing moving fronts involving topological changes; total variation and other partial differential equations based image processing techniques. Dr. Osher has been a Fulbright Fellow, Alfred P. Sloan Fellow, SERC (England) Fellow, U.S. - Israel Binational Fellow, received NASA Public Service Groups Achievement Award, and was an invited speaker at the International Congress of Mathematicians.
