【摘要】 本文基于[2]中的最优盲水印检测方案,从编码的角度显著改进了水印的稳健性。我们考察了使用不同编码方案嵌入的水印的抗攻击性能,得出了合适的编码方案会显著提高水印稳健性的结论,最后通过实验比较了使用不同编码方案嵌入时,经过几种常见的水印攻击后,水印图像的稳健性,证实了按01或10顺序交错的编码嵌入方案不但简便易行,而且在提高水印的综合抗攻击性能上表现最好。更多还原

【Abstract】 Base on the framework for optimal blind watermarking proposed in paper[2],we improve the robust of the watermarking by considering coding.After several coding scheme is studied,we conclude that proper coding would improve the robust of watermarking obviously.In the end,we comparing the different coding scheme by experiments,its result improved that the coding scheme of encoding 0 or 1 to 010101... or 101010... is not only easy to operate,but also has the best performance in resisting various attacks.更多还原
