Abstract :
This work describes an automatic approach to recover a high quality surface mesh from low-quality
or oversampled inputs (STL-files) obtained from medical imaging through classical segmentation
techniques. The approach combines a robust method of parametrization based on harmonic maps
with a recursive call to a multi-level edge partitioning software. By doing so, we are able to get rid
of the topological and geometrical limitations of harmonic maps. The overall remeshing procedure
is implemented, together with the ïnfinite element discretization procedure required for computing
harmonic maps, in the open-source mesh generator Gmsh. We show that the proposed method
produces high quality meshes and we highlight the benefits of using those high quality meshes for
biomedical simulations.
