Abstract: In order to compromise the robustness and transparency of watermarked 3D meshes, proposed a zero-watermarking algorithm could be used in meshes with any topological connectivity. Watermarking signal was constructed by geometric data of mesh, after geometric feature extracting in spatial domain and energy's convergence in transformed domain. Experimental results show the watermark constructed by proposed algorithm can resist vertex reordering, translating, rotating, uniformed scaling, and show good robustness against adding noise and mesh simplifying. 

Key words: information processing, 3D watermarking, mesh watermarking, zerowatermark
