Seminar Level set methods

Di, 14-16, 5701.EG.026 (IMETUM-Hörsaal im Medizintechnikgebäude)

Prof. O. Junge

Level set methods are numerical techniques for tracking geometric objects which change their shape. The underlying powerful idea is to represent the $$n-1$$-dimensional boundary of an $$n$$-dimensional object under consideration as the zero level set of a scalar function $$\varphi$$ on $$\mathbb{R}^n$$ which additionally depends on time. Solving an associated partial differential (evolution) equation for $$\varphi$$ (a Hamilton-Jacobi equation) numerically, one implicitely obtains the evolution of the object in terms of the zero level set. These methods have been developed in the 1980s and have since then been applied in numerous applications like fluid dynamics, image processing, computational geometry and materials science.
