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...

Topology Correction Using Fast Marching Methods and Its Application to Brain Segmentation
We present here a new method for correcting the topology of objects segmented from medical images. Whereas previous techniques alter a surface obtained from the hard segmentation o...

Restoration of the Sphere-Cortex Homeomorphism
Abstract. The proposed algorithm has been developed as a pre-processing tool for inflating cortical surface meshes, which have been created using segmentation and subsequent triang...

Topologically correct reconstruction of tortuous contour forests
Electrophysiological modeling of dendrites and other neurological processes is generally done in a simplified manner, by treating these structures as a series of cylinders (aka ca...

Topology Smoothing for Segmentation and Surface Reconstruction
Abstract. We propose a new method for removing topological defects in surfaces and volumes segmented from medical images. Unlike current topology correction approaches, we define a...
