摘要: 对基于奇异向量鲁棒性的水印方法做质量补偿可在一定程度上提升水印的不可视性,质量补偿效果取决于补偿参数。为了优化补偿参数,通过分析水印方法的嵌入原理,找出载体像素值变化与奇异向量变化之间的关系,研究质量补偿前后像素的改变规律,从而给出最优补偿参数值,并分析质量补偿与鲁棒性的关系及影响质量补偿效果的因素。实验部分验证了质量补偿效果,
通过与同类方法的比较,表明该质量补偿方法可以提升水印方法的性能。

Abstract: The quality compensation for the watermarking method based on the singular matrix robustness can improve the invisibility of watermarks to some extent. To optimize the compensation parameters, the paper analyzes the embedding principle of the watermarking method, finds out the relationship between pixel modifications and singular matrix changes, and studies the variation rules of pixels before and after quality compensation, thereby obtaining the optimal compensation parameters. Based on the optimal parameters, the paper further studies the relationship between quality compensation and robustness, and determines these factors that affect the compensation effect. The final experiments verify the quality compensation effect, and the comparison with similar methods proves that the proposed quality compensation method can improve the performance of watermarking.



Key words: robust watermarking, singular value decomposition, quality compensation
