Blind robust watermarking schemes based on 3D mesh object
基于三维网格物体的鲁棒性盲水印方案

A new method for blind robust 3D mesh object watermarking applications was proposed. First, a transformation of the model to an affine invariant space was finished prior to watermark embedding. Then the Cartesian coordinates was converted to spherical coordinates in which the watermark was embedded. In affine invariant space, the 3D object is not affected by geometric transformations, such as translation, rotation and scaling. So the proposed method is robust enough to geometric transformations, which is proved by experimental results. The method is good at visual masking too.
