本文提出了六种基于曲波变换的鲁棒非盲水印方案。文献1提出了一种单波段水印算法。本文在单波段水印算法的基础上，加入人类视觉系统（HVS），形成了六种不同的多波段水印算法。随着水印冗余度的增加，该算法的鲁棒性将被研究，并与单带水印进行比较研究。实验结果表明，所提出的算法对各种成像攻击具有很强的鲁棒性。
In this paper, six robust non-blind watermarking schemes based on curvelet transform are proposed. Single band watermarking method was proposed in Ref. 1. This paper develops the single band watermarking method and adds Human Vision System (HVS) to form six different multi-bands watermarking methods. With the increasing redundancy of watermark, the robustness of the algorithm will be investigated and comparative studies with the single band watermarking will be shown. The experimental results demonstrate that the proposed algorithms have great robustness against various imaging attacks.
