A blind watermarking quantification algorithm based on Arnold transformation of wavelet domain

本文提出了一种基于的小波域盲水印量改进算法,通过实验表明,该方法所隐藏的水印具有良好的抗攻击性。首先,为提高水印安全性要利用Arnold变换使水印图置乱,结合Xie和Kundur的量化算法,最后为了平衡鲁棒性和不可见性,分别在低频、高频上经不同策略嵌入一部分水印。

This paper presents an improved algorithm based on wavelet domain blind water print runs,the ex-periments show that this method is hidden watermark has good resistance to attack.First of all,in order to improve watermark security to use Arnold transform to make watermark scrambling,combined with Xie and Kundur quantization algorithm,finally in order to balance the robustness and invisibility,respectively by different strategies on low frequency high frequency part of embedded watermark.
