| 摘 要： | 近年来,图像置乱技术被广泛地应用在数字水印中.文中分析了典型置乱算法的性能,验证了其作用.实验表明,由于Arnold变换计算简单,迭代较小的次数就可以获得较好的置乱效果,因此更适合在水印中应用.同时,在水印图像经过Arnold置乱预处理的情况下,当含水印图像的面积被剪切掉3/4时,提取出来的水印仍然比较清晰,所以采用置乱技术,很大程度上提高了水印的鲁棒性. |

| Abstract: | Image scrambling has been widely used in Digital Watermarking.This paper analyzes the performance of typical scrambling algorithm and verifies its effectiveness.Experimental results shows that Arnold transformation fits for the application in digital watermarking.The better image scramble effect could be obtained with simple Arnold calculation.Meanwhile,with Arnold pre-processing,even if the 3/4 area of watermark image is cut off,the abstracted image is still recognizable.With Arnold transformation scramble... |
