| 摘 要： | 三维网格模型本身包含了多种冗余信息,利用三角面片3个顶点排列顺序的冗余信息,嵌入水印信息,提取水印信息时,不需要提供原始模型。实验表明,该算法能有效抵抗平移、旋转、缩放、噪声等攻击。

| Abstract: | There are much redundant information about 3D mesh model,such as arrangement of three vertices of a triangle face.With keeping the normal vector of the triangle unchanged,we embed watermarking information by adjusting the order of three vertices.Original model needn't offered during extracted watermarking.Experiments show that this algorithm can effectively resist against translation,rotation,scaled,noising. |
