论文摘要
随着编辑和通过互联网共享图像的增长，保护图像作者身份的重要性有所增加。强大的水印是维持版权保护的已知方法。鲁棒性和不可察觉性是试图通过水印来最大化的两个因素。通常，这两个参数之间存在权衡。提高鲁棒性将减少水印的不可识别性。本文提出了一种自适应方法，该方法决定了封面图像中有关其质地和亮度的不同部分中嵌入水印的强度。自适应嵌入会增加鲁棒性，同时保留水印图像的质量。实验结果还表明，所提出的方法可以有效地以不同种类的常见水印攻击重建嵌入式有效载荷。与最近的技术相比，我们提出的方法表现出良好的性能。
With the growth of editing and sharing images through the internet, the importance of protecting the images' authorship has increased. Robust watermarking is a known approach to maintaining copyright protection. Robustness and imperceptibility are two factors that are tried to be maximized through watermarking. Usually, there is a trade-off between these two parameters. Increasing the robustness would lessen the imperceptibility of the watermarking. This paper proposes an adaptive method that determines the strength of the watermark embedding in different parts of the cover image regarding its texture and brightness. Adaptive embedding increases the robustness while preserving the quality of the watermarked image. Experimental results also show that the proposed method can effectively reconstruct the embedded payload in different kinds of common watermarking attacks. Our proposed method has shown good performance compared to a recent technique.
