Abstract

Abstract: A new watermarking scheme for the copyright protection of 3D mesh models was proposed. In this scheme, the geometric signal processing theory was adopted to transform 3D mesh signals into planar regularly sampling signals, and then Singular Value Decomposition (SVD) technique was employed to embed watermark. Experimental results show that the proposed algorithm has better imperceptibility and stronger robustness.
