基于三维网格模型的双重数字盲水印算法
Dual Digital Blind Watermark Algorithm Based on Three-dimensional Mesh Model
摘要
Abstract
A robust dual digital blind watermark is proposed based on three-dimensional mesh model in order to solve the weakness of the single watermark's difficulty to resist against various attacks. The scheme embeds the watermark by modifying the location of vertices in their related space and topological information of 3D mesh, which makes the model resist not only large scaled cropping operation but also high strong noising. With this approach, the original model is not required during detecting watermarks. Experimental results show that the algorithm has good visualizing quality and robustness which can be against the attacks such as translation, rotation, scaling, model cropping and vertex permutation etc.关键词
