Laplacian spectral distances and kernels on 3D shapes ?
Design and discretization of Laplacian spectral distances on 3D shapes. Smoothness and shape-intrinsic properties through filtered Laplacian eigenvalues. Higher approximation accuracy and lower computational cost than previous work. Spectrum-free computation bypasses computational and storage limits.
