  1. Laplace–Beltrami eigenvalues and topological features of eigenfunctions for statistical shape analysis

    Computer-Aided Design 41(10):739 (2009)

    This paper proposes the use of the surface-based Laplace–Beltrami and the volumetric Laplace eigenvalues and eigenfunctions as shape descriptors for the comparison and analysis of shapes. These spectral measures are isometry invariant and therefore allow for shape comparisons ...
