【摘要】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 algorithm,finally
