Paper Abstract

In a recent paper, we have introduced a topological descriptor for shape representation based on classical Morse theory. More precisely, given a manifold M and a Morse function f on M, we build an invariant [Morse Shape Descriptor (MSD)] of the manifold from the ranks of relative homology groups of all pairs of lower levels of the function f. While the MSD is a robust invariant with very nice properties, its application requires time consuming computations of homology groups. We present a new and computationally efficient method to capture the essential of the information given by the MSD.
