Topologically correct surface reconstruction using alpha shapes and relations to ball-pivoting
The problem to reconstruct a surface given a finite set of boundary points is of growing interest, e.g. in the context of laser range images. While a lot of heuristic methods hav...

A Multi-scale Geometric Flow for Segmenting Vasculature in MRI
Often in neurosurgical planning a dual echo acquisition is performed that yields proton density (PD) and T2-weighted images to evaluate edema near a tumour or lesion. The developme...

Deformable Surfaces for Feature Based Indirect Volume Rendering
In this paper we present an indirect volume visualization method, based on the deformable surface model, which is a three dimensional extension of the snake segmentation method. I...
