Paper Abstract

Over the past decade, very fruitful efforts have converged to offer tools devoted to the processing of meshes. Spectral decomposition of mesh geometry has first found its applications in both filtering and mesh partitioning. It has been lately extended to address transmission and watermarking issues. Such a decomposition gives rise to pseudo-frequential 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 a lapped spectral representation for compression and watermarking purposes.
