• Abstract:

  the digital watermarking algorithm for 3D mesh model is studied, the traditional algorithm can not solve the contradiction between invisibility and robust, in order to improve the safety of the 3D mesh model, this paper proposed a 3D mesh watermarking algorithm by singular value decomposition algorithm. Firstly, he matrix formed by the distance from the apex of the three-dimensional grid model to its center is used as vertical modular matrix, and then the singular value decomposition algorithm is used to handle the matrix, lastly, the watermark signal is embedded into the diagonal matrix to 3D mesh models containing the watermark signal. The simulation results show that the proposed algorithm has solved the problem in the traditional algorithm, can resist various attacks, and strengthen the copyright protection of 3D mesh model.
