Automatic 3D Face Recognition Using Topological Techniques
In this paper, we use the three-dimensionaltopological shape information for human face identification. We propose a new method to represent 3D faces as a topological graph. Fine...

Computing Polygonal Surfaces from Unions of Balls
We present a new algorithm for computing a polygonal surface from a union of balls. The method computes and connects the singular points of a given union of balls in an efficient ...

Empty interior Recurrence for Continuous Flows on Surfaces
In this paper we characterize topologically the empty interior subsets of a compact surface S which can be -limit sets of recurrent orbits (but of no nonrecurrent ones) of continu...

Fast and Accurate Phylogeny Reconstruction Algorithms Based on the Minimum-Evolution Principle
This paper investigates the standard ordinary least-squares version 24 and the balanced version 20 of the minimum evolution principle. For the standard version, we provide a greedy...

Learning smooth shapes by probing
We consider the problem of discovering a smooth unknown surface S bounding an object O in R3 . The discovery process consists of moving a point probing device in the free space ar...
