An image watermarking algorithm in DWT domain is proposed which is robust against geometric distortion. We hide 536 information bits in a 512×512×8 image. The merits of the proposed algorithm are as follows: 1) By introducing distance between the attacked image and the original image, we can resynchronize the data extraction based on the minimum distance; 2) Using multi-resolution matching and coarse-fine searching to prune the searching space, the computation of our algorithm is drastically reduced; 3) Wit...             提出了一个基于DWT的有意义稳健图像水印算法 .1)采用基于最小距离的水印重同步技术 ,能抵抗RST ,shearing ,generallineartransformation等几何攻击 ;2 )采用多分辨率匹配和粗细搜索相结合的方法 ,有效降低算法的计算量 ;3)应用二维交织技术和BCH编码 ,具有纠正随机错误和突发错误的能力 .把一个 5 36bits信息构成的字符串水印嵌入到 5 12× 5 12× 8bits的图像中 ,所实现的水印在抵抗StirMark攻击中达到了较好的性能 .相对于目前的一些水印算法 ,具有隐藏数据量大且好 ,对抗几何变换具稳健性等优点 . 文摘来源          Reviews on watermarking against geom etric distortion were given, and proposed a robust watermarking algorithm agains t geometric distortion in DWT domain was proposed in this paper.
