Resist-geometric-attacks
该算法把计算出的图像不变质心作为对其进行对数极坐标变换的原
点, 再作傅立叶变换, 取出中频段幅值作为水印嵌入域。该算法具有较好的鲁棒性、可检测性, 能同时抵抗几何攻击和信号
处理攻击, 它在数字图像的版权保护等领域有广泛的应用前景。(The algorithm to calculate the heart of the image does not degenerate as the number of its polar transformation of the origin, further Fourier transform, remove the watermark embedding in the frequency domain as amplitude. The algorithm has better robustness, detectability, can also resist geometric attacks and signal processing attacks, which in the digital image copyright protection and other fields have a wide range of applications.)
