pyFM.signatures.WKS_functions.mesh_WKS

pyFM.signatures.WKS_functions.mesh_WKS(mesh, num_E, landmarks=None, k=None)

Compute the Wave Kernel Signature for a mesh.

Parameters:

• mesh (TriMesh) – Mesh on which to compute the WKS.

• num_E (int) – Number of energy values to use.

• landmarks ((p,) np.ndarray, optional) – Indices of landmarks to use.

• k (int, optional) – Number of eigenvalues to use.

Returns:

WKS – Array where each line is the WKS for a given energy value.

Return type:

(N, num_E) np.ndarray
