A Novel 3D Mesh Blind Watermarking Algorithm Based on Nielson Affine Invariant Norm

In this paper, a novel blind watermarking method for 3D model is proposed based on Nielson affine invariant norm. In our method, the affine invariance is computed for each vertex firstly. At next, we get grouping of them by using clustering algorithm. Then, one bit of watermark is embedded to each group using QIM method. Experimental results indicate the ability of the proposed method to deal with the 3D affine transformation, noising, vertices recomposition and their combined attacks.
