Fast Extraction of Tubular and Tree 3D Surfaces with Front Propagation Methods
We present a new fast approach for surface segmentation of thin structures, like vessels and vascular trees, based on Fast Marching and Level Sets methods. Fast Marching allows se...

Finding Line Segments by Surface Fitting to the Hough Transform
We describe a method based on the Hough transform to compute a set of parameters that completely describe line segments. By complete, we mean the description includes the endpoint...

On stars and Steiner stars
A Steiner star for a set P of n points in Rd connects an arbitrary point in Rd to all points of P, while a star connects one of the points in P to the remaining n - 1 points of P....

On stars and Steiner stars. II
A Steiner star for a set P of n points in Rd connects an arbitrary center point to all points of P, while a star connects a point p P to the remaining n-1 points of P. All connec...
