Abstract :
A novel blind watermarking method on 3D meshes is proposed in this paper. PCA (primary component analysis) is used for 3D meshes ´preprocessing. Octree structure is obtained after octree partition of 3D meshes. Meaningful watermark is then embedded into SC (Single Child) nodes in bottom level of octree. This method is robust against translation, rotation, uniform scaling and vertex reordering attacks with a big embedding space. Higher nodes of octree are used to construct ´zero-watermark´, which can resist simplification, noise and remeshing attacks. This method can be used directly on point cloud as it does nothing with topology of meshes.
