Reeb graphs for shape analysis and applications (2008, methodology): “Related concepts are also dealt with in [78], where a Morse function with a user-controlled number and configuration of critical points is computed by solving a relaxed form of Laplace’s equation, and is used to build Morse complexes.”
Technical Section: Discrete Laplace-Beltrami operators for shape analysis and segmentation (2009, methodology): “Spectral methods have recently gained much interest in computer graphics [62], with applications that include mesh compression [30], parametrization [25,43], segmentation[31,35], remeshing [17], filtering [34,57],”
