The Wave Kernel Signature characterize each point of a 3D shape. Each value of the WKS can be intepreted in the framework of quantum mechanic as the average probability to find a particle of a given energy at a given point. Mathematicaly, the WKS is based on the eigen-functions and eigen-values of the Laplace-Beltrami operator on the shape It provides an optimal combination of the eigen-functions values to construct a disciminative and robust descriptor.


You can download a matlab function which compute the WKS of all points of a shape given a set of vertices and faces here
