Lapped spectral decomposition for 3D triangle mesh compression

Spectral decomposition of mesh geometry has first been introduced by Taubin for geometry processing purposes. It has been extended to address transmission issues by Kami & Gotsman. Such decompositions give rise to pseudofrequential information of the geometry defined over the mesh connectivity....

description Spectral decomposition of mesh geometry has first been introduced by Taubin for geometry processing purposes. It has been extended to address transmission issues by Kami & Gotsman. Such decompositions give rise to pseudofrequential information of the geometry defined over the mesh connectivity. For large meshes a piecewise decomposition has to be applied in order to restrict the complexity of the transform. In this paper, we propose to introduce overlap for its spectral representation. We show visual gains obtained in compression and progressive transmission of mesh geometry.
