Abstract

Digital watermarking for 3D meshes is a means to copyright protection. In this paper, we propose a robust watermarking algorithm for 3D Meshes. We work on multiresolution, triangular and semi regular meshes having various sizes. Our algorithm is able to insert high amount of information in the field of multiresolution . For this reason, we apply a uniform scalling then a wavelet transform to the host mesh. Embedding step consist on modifying wavelet coefficients vector according to the bit to be inserted. These techniques do not generate a quality degradation of the mesh despite the important capacity adopted. Tests applied to various attacks have shown the robustness of our algorithm against rotation, translation, uniform scaling, Noise addition, smoothing, simplification and coordinate quantization. A comparison with literature revealed that we have a remarkable improvement over the published results.
