| 摘 要： | 提出一种基于实数傅里叶变换的数字水印新算法，利用Arnold变换将水印图像置乱，再将置乱后的二值水印嵌入到实数傅里叶变换域的相位中。实验结果表明，该算法具有良好的不可见性，对JPEG压缩、加噪等常见攻击具有鲁棒性。

| Abstract: | A new image watermarking algorithm based on real discrete Fourier transform is proposed in the paper. Arnold iterative transform is used to disarray the watermarks before embedding, and then the disarrayed watermarks with binary random sequences are embedded into the phase components of real Fourier transform field. Experimental results demonstrated that the algorithm has better invisibility and is robust to the attacks such as JPEG compression, noise addition. |
