3D polygonal meshes watermarking using normal vector distributions

We proposed 3D polygonal meshes watermarking using normal vector distribution to robust against various attacks. The norm vector distribution of mesh is a consistent factor that is robust against various attacks. After calculating these distributions of 6 patches respectively, the same watermark bits are embedded into the same ordered bins in the distributions of 6 patches. The experiment shows that the watermark is imperceptible and robust against various attacks.
