Schedule Fall 2004
Monday, September 27, 2004: Gerd Teschke, University of Bremen, Germany,
"Wavelets and variational principles in image processing".
Monday, October 4, 2004: Yalin Wang, Mathematics UCLA,
"Computational Conformal Geometry for Brain Mapping",
Abstract: We developed a general method for global surface
For genus zero surface, our algorithm can find a conformal mapping
two genus zero manifolds by minimizing the harmonic energy. We apply this
algorithm to the cortical surface matching problem. We further extended
algorithm to find a 3D volumetric harmonic map from a 3D brain volumetric
to a solid sphere. We proposed a new algorithm, sphere carving method,
can build 3D tetrahedral mesh from a set of images with topology
New research on surface matching and 3D face recognition will be
and experimental results will be reported.
Monday, October 11, 2004: Roland Wilson, University of Warwick, UK, visiting IPAM,
Multiresolution Random Field Models for Image Processing.
Monday, October 18, 2004: Marc Droske, Germany, Level Set techniques for multimodal image registration and
implicit formulations for fourth-order geometric diffusion problems.
Abstract: A method for the registration of a pair of images of different
modalities is presented. It is based on a variational formulation
depending on the image morphology rather than intensity based properties
of the images, motivated by the assumption that at least geometric
features of the images are similar. In addition to the alignment of
morphologies a coupled free discontinuity problem based on the
Mumford-Shah functional is used to enhance alignment of dominant edges.
In the second part of the talk an overview of level set based
gradient flows of, possibly anisotropic, geometric energies will be
given and results be presented.

method and nonlinear optimization methods such as Augmented Lagrangian and
Log Barrier methods. I will show how practically these problems can be
