摘要:
提出了奇异值分解算法的改进方案.结合人类视觉模型给出了盲水印算法嵌入水印强度的上界,并确定了在不同水印强度下抗攻击能力的界限.利用奇异值分解在保证图像质量无失真的条件下嵌入高强度水印,并利用Turbo码的强纠错能力抵抗攻击和提取水印.试验表明本方案在JPEG压缩、剪切、中值滤波、随机噪声和椒盐噪声等常见攻击下都能表现出良好的鲁棒性.
Abstract:
An im proved schem e o f singular-value decomposition algor ithm is presented. Comb ined w ith human v ision system ( HVS), the uppe r boundary o f embedded strength in b lind w aterm arking a lgor ithm is g iven, and the boundary o f anti-attack ab ility in different wa term ark ing streng th is determ ined. H igh streng th wa term ark is embedded in by using singu la r-va lue decomposition, w hile ensur ing the im age qua lity. At last use the high error-co rrecting pe rfo rm ance o fTur bo code to anti-a ttack and ex tract wa term ark. Exper imenta l resu lt show s that the schem e is robust w ith the trad itiona l a t tacks inc lude JPEG com pression, cropp ing, mean filter, random no ise and pepper-and-sa lt-no ise.
