摘要：
This paper presents a robust 3D mesh watermarking method based on planar parameterization and DCT. Firstly, a planar parameterization algorithm is used to map 3D mesh models to 2D parametric meshes. Geometric signals are then transformed into 2D signals. Then a DCT-based watermark scheme is proposed to embed the watermark into some DCT coefficients. The algorithm adopts a nonblind extraction process to retrieve the watermark. Experiments show that this method is robust against common attacks such as adding noise attacks, uniform affine transformation attacks.
