Steklov Spectral Geometry for Extrinsic Shape Analysis
ACM Trans. Graph., 2019.
Dirichlet-to-Neumann operator Shape analysis Steklov eigenvalue problem geometry processing
We propose using the Dirichlet-to-Neumann operator as an extrinsic alternative to the Laplacian for spectral geometry processing and shape analysis. Intrinsic approaches, usually based on the Laplace–Beltrami operator, cannot capture the spatial embedding of a shape up to rigid motion, and many previous extrinsic methods lack theoretical ...More
