Alpha-Beta Witness Complexes

13 years 11 months ago

Download www.cs.duke.edu

Building on the work of Martinetz, Schulten and de Silva, Carlsson, we introduce a 2-parameter family of witness complexes and algorithms for constructing them. This family can be ...

Geodesic Delaunay triangulation and witness complex in the plane

13 years 6 months ago

Download graphics.stanford.edu

We introduce a new feature size for bounded domains in the plane endowed with an intrinsic metric. Given a point x in a domain X, the homotopy feature size of X at x measures half...
