For the three-dimensional (3D) mesh watermarking, the trade-off between the robustness and transparency has been pursued by researchers. In this paper, a blind watermarking algorithm is proposed to improve the robustness by embedding the stronger watermark while ensuring a good performance in the transparency. In the embedding process, we choose the distance from the vertex to the model center as the eigenvalue. Eigenvalues are divided into the corresponding bins according to the improved vertex grouping method, which enhances the robustness of the watermark in the marginal bins. In the process of adjusting vertices, the proposed algorithm effectively controls the transparency of 3D models by the piecewise mapping function. The experimental results demonstrate that the proposed approach is remarkably robust against common attacks including rotation, translation, uniform scaling, vertex reordering, noise, smoothing, quantization and subdivision. |
