Paper Abstract

Due to massive development of 3D meshes exchanges on the Internet, transmission and protection of such data has recently received a special focus. In this paper we present a method to compress and watermark the geometry of a 3D triangle mesh in the mesh spectral domain. We first explain how to improve the quality of the compression using overlapping, then we propose a substitutive watermarking scheme in the mesh spectral domain. Finally, we give an overview of the results obtained both for compression or watermarking. The robustness of the watermarking algorithm against the compression method is demonstrated.
