摘要:
提出了一种基于三维模型网格子集的新型盲水印算法。算法以三维模型网格中的网格子集为载体，提取三维模型的三角形面片数据，根据三角形相似四元组（TSQ）法计出边长比和宽高比，通过阈值控制定位嵌入基元，最后根据水印信息值修改网格子属性ID嵌入水印。水印提取过程则通过对嵌入基元定位后，查询属性ID值计算完成。实验结果表明：该算法对于几何变换和剪切、噪声攻击等都具有较好的鲁棒性。
Abstract:
A new blind watermarking scheme based on the mesh subsets of 3D models was proposed, in which the mesh subsets of 3D models were utilized as the vector and triangular surface data of 3D modes were extracted. The triangle’s height to width ratio was computed in accordance with the method of triangle similarity quadruple (TSQ). The hideouts to be embedded were located via threshold control. Watermark was embedded by modifying the attributes of the mesh subsets in accordance with the watermark data. The watermark was extracted by computing the ID of the subsets. Experimental data have confirmed the robustness of the algorithm.
