摘要: 结合Arnold变换,提出了一种基于图像置乱变换的空域水印算法,对置乱变换参数进行了选择,给出了选择依据。攻击实验和性能对比实验表明,该算法对大范围内剪切、随机擦除和高强度噪声攻击具有强稳健性,优于传统的空域水印算法。

Abstract: Combined with Arnold transformation, this paper proposes a spatial domain image watermarking algorithm based on scrambling transformation and gives the methods of how to select proper scrambling transformation variables. The experiments of the attack and performance comparison show it is very robust in keeping resilience to cutting attack in a large area, random erasing and noise attack with high intensity, and it is superior to the classic spatial domain watermarking algorithms.
