3D Subdivision Mesh Watermarking Base on DCT and FFT

摘要：

A new robust watermarking 3D subdivision mesh model algorithm is presented in this paper. We embed watermarks into a 3D subdivision mesh based on DCT and FFT. In order to keep the mesh transparency, we do not directly embed watermarks into vertex coordinate of mesh but into a gray image using FFT. The algorithm is applied to many mesh models. Experiments show that this algorithm is robust against some attacks, such as translation, rotation, cropping, local noising and combine attack of local noising and cropping.
