Abstract

We developed a general method for global surface conformal 
parameterization.  For genus zero surface, our algorithm can find a 
conformal mapping between any two genus zero manifolds by minimizing 
the harmonic energy.  For high genus surface, our algorithm can find 
its global conformal parameterization by computing cohomology and 
holomorphic 1-form.  We apply this algorithm to the cortical surface 
matching problem.  We further extended the algorithm to find a 3D 
volumetric harmonic map from a 3D brain volumetric model to a solid 
sphere.  We proposed a new algorithm, sphere carving method, which can 
build 3D tetrahedral mesh from a set of images with topology 
preservation.  New research on surface matching will be discussed and 
experimental results will be reported.
