In recent years, quantities derived from the heat equation have become popular in shape processing and analysis of triangulated surfaces. Such measures are often robust with respect to different kinds of perturbations, including near-isometries, topological noise and partialities. Here, we propose to exploit the semigroup of a Schr\"{o}dinger operator in order to deal with texture data, while maintaining the desirable properties of the heat kernel. We define a family of Schr\"{o}dinger…

A Gromov-Hausdorff Framework with Diffusion Geometry for Topologically-Robust Non-rigid Shape Matching
TLDR
This paper explores the applicability of diffusion distances within the Gromov-Hausdorff framework and finds that in addition to the relatively low complexity involved in the computation of the diffusion distances between surface points, its recognition and matching performances favorably compare to the classical geodesic distances in the presence of topological changes between the non-rigid shapes.
Discrete laplace operator on meshed surfaces
TLDR
This paper proposes the first algorithm for approximating the Laplace operator of a surface from a mesh with point-wise convergence guarantees applicable to arbitrary meshed surfaces and shows that for a sufficiently fine mesh over an arbitrary surface, the mesh Laplacian is close to the La place-Beltrami operator on the surface at every point of the surface.
A Concise and Provably Informative Multi‐Scale Signature Based on Heat Diffusion
TLDR
The Heat Kernel Signature, called the HKS, is obtained by restricting the well‐known heat kernel to the temporal domain and shows that under certain mild assumptions, HKS captures all of the information contained in the heat kernel, and characterizes the shape up to isometry.

TLDR
Both theoretically and in quantitative experiments it is demonstrated that the WKS is substantially more discriminative and therefore allows for better feature matching than the commonly used Heat Kernel Signature.
