A heat kernel signature (HKS) is a feature descriptor for use in deformable shape analysis and belongs to the group of spectral shape analysis methods. Abstract. We propose a novel point signature based on the properties of the heat diffusion process on a shape. Our signature, called the Heat Kernel Signature. The Heat Kernel Signature is an approach, which is well suited for this kind of problem.

In this work we propose a generalization of the Heat Kernel Signature (HKS).

Here, we extend the idea of heat kernel signature to robust isometry- invariant volumetric descriptors, and show their utility in shape retrieval.
