In order to improve performance of resistance to the geometrical attack while keep invisible, a zero-watermark algorithm for digital image based on Fourier-Millin transforming is proposed.
为了提高抗几何攻击性能，同时保证不可见性，提出了一种结合傅立叶-梅林变换和零水印概念的图像水印算法。
The experimental results have shown that the proposed watermark is invisible to human eyes and very robust to joint photographic experts group compression attack, crop attack and so on.
实验结果表明该算法具有良好的不可视性和抗联合图像专家组压缩、剪切、滤波等攻击的能力。
