Shape Partitioning via L Compressed Modes

Martin Huska, Damiana Lazzaro, Serena Morigi

The eigenfunctions of the Laplace Beltrami operator (Manifold Harmonics) define a function basis that can be used in spectral analysis on manifolds. In [21] the authors recast the…

On multi-degree splines

Carolina Vittoria Beccari, Giulio Casciola, Serena Morigi

Multi-degree splines are piecewise polynomial functions having sections of different degrees. For these splines, we discuss the construction of a B-spline basis by means of integra…
