Abstract

First, the algorithm converts 3d models into an affine invariant space, in order to obtain rotation in-variance and scale in-variance of the model; then we transform the distance of the grid point to the center to a signal in frequency domain using one-dimensional DFT. We embed a watermark into the signal in frequency domain, and then transform it back to a digital signal in spatial domain. Finally, according to the value of the new spatial signal, we modify the coordinates of points on the grid to get the digital watermark grid. Experimental results show that the algorithm can resist similar mesh simplification, plus noise and shearing attacks, and has good robustness.
