Abstract

the main objective of 3D mesh watermarking is to maximize the watermark strength while minimizing the visual distortion. In this paper, we propose a novel 3D mesh watermarking based on the human visual system and mesh curvature. We analyze the region’s mean curvature and fluctuation of curvature, and then choose the appropriate regions with high visual masking degree, in order to embed the watermark by using the Interpolation Algorithm. The experimental results show that the watermark is capacious, invisible and robust against various attacks.

一种新颖的鲁棒三维网格水印算法

三维网格水印的主要目标是使水印强度最大化，同时使视觉失真最小化。本文提出了一种基于人眼视觉系统和网格曲率的三维网格水印算法。首先分析区域的平均曲率和曲率波动，然后选择合适的视觉掩蔽度高的区域，利用插值算法嵌入水印。实验结果表明，该水印具有容量大、不可见性好、抗各种攻击能力强的特点。
