一种基于小波变换的三维网格模型水印算法

In this paper, we proposed a robust watermarking algorithm for 3D mesh. The algorithm was based on wavelet transform. A planar parameterization algorithm was first proposed to map 3D mesh models to 2D parametric meshes. Geometric signals were then transformed into 2D signals. Then a wavelet-based watermark casting scheme was proposed to embed the watermark into some wavelet coefficients, Experimental results show that the embedded watermark is robust against various geometry signal processing attacks.
