摘    要:针对三维网格模型的版权保护提出了一种新的基于奇异值分解(SVD)的数字水印算法。算法利用几何信号处理框架将三维几何信号转换成平面规则采样信号,再用SVD技术嵌入水印。实验结果表明,算法具有较好的透明性和鲁棒性。

关 键 词:三维网格模型    鲁棒性    奇异值分解    版权保护    数字水印

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.
