针对现有大部分水印算法无法实现全盲检测的局限性,本文提出了一种基于自嵌入技术的全盲鲁棒图像水印算法。算法通过自嵌入的特征水印和盲提取的认证水印来实现水印的完全盲检测。实验结果表明,提出的水印算法在满足水印不可觉察性的同时,对于一些常规的图像处理攻击具有比较理想的鲁棒性。
Due to the majority of current robust watermarking algorithms couldn't achieve totally blind detection,a robust watermarking algorithm based on self-embedding technique with totally blind detection was proposed in this paper.The proposed algorithm realizes totally blind detection by calculating the correlation coefficient between the self-embedding feature watermark and the blindly extracting authentication watermark.The experimental results show that the proposed watermarking algorithm has strong robustness to resist various common image processing attacks while keeping invisibility of the embedded watermark.
