摘　　要：本文提出了一种基于图像纹理特征的自适应水印算法.首先通过原加载水印图像与小波变换后的高频子带进行结合,重构出新水印序列,然后通过自适应阈值算法决定水印的嵌入和提取.经实验证明这种算法具有很好的不可见性,对常见的攻击具有较好的鲁棒性.This paper presents an adaptive watermarking algorithm based on image texture features.Firstly,the watermark image is combined with the high frequency sub band after wavelet transform,reconstructing a new watermark.Then,the watermark embedding and extraction are determined by the adaptive threshold algorithm.The experimental results show that the algorithm has good invisibility as well as good robustness against common attacks.
