Broad Area Colloquium For AI-Geometry-Graphics-Robotics-Vision
The Level Set Method - What's In It For You?

Monday, October 14, 2002, 4:15PM
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.
