Digital Watermarking of Compressed 3D Meshes

International audienceThis paper presents a robust watermarking algorithm applied to 3D compressed polygonal meshes. Copyright protection of 3D models becomes very important for many applications using public networks. As some recent compression techniques allow very high compression rates, it is of interest to verify that watermarking techniques support this kind of attack. In this paper we present the complete scheme developed: the compression algorithm, the watermarking algorithm and the mark extraction process
