Blind invisible watermarking for 3D meshes with textures
We propose to embed watermarks by modifying the texture mapping information of 3D models rather than modifying the geometry information or texture image as existing works do. We present a blind watermarking method based on spectral decomposition that incorporates the process of Texture Image Compensation (TIC) which ensures no visual distortion. We describe a Neighbor Couple Embedding (NCE) scheme that works on the Manifold Harmonics Transform (MHT) of the texture coordinate functions. Experiments show that this method is robust against common attacks such as adding noise attacks, uniform affine transformation attacks, local modification attacks and produces no visual distortion on the rendered 3D models. Our contributions include watermarking the texture mapping information with no visual distortion as well as a novel embedding method that is robust against various possible attacks.
