摘要
第二代数字水印技术是解决水印抗几何攻击这一难题的有效方法。本文在总结分析现有抗几何攻击算法和不足的基础上,阐述了第二代数字水印的概念,探讨了第二代水印算法中特征点和特征区域选取问题,并对可能的研究方向进行了展望。
The second generation digital watermarking is effective in solving the problem of how to improve the robustness to geometric attacks. This paper summarized current algorithms against geometric attacks and analyzed their deficiency, then explained the concept of second generation digital watermarking, discussed the selection of feature points and feature areas. Finally we drew a conclusion and presented the probable development directions.
