摘要:
提出一种小波域中具有旋转、平移和尺度不变性的第二代图像水印技术。水印信号由原始图像产生,在水印检测前,利用原始图像的矩信息估计水印图像所经过的旋转、平移和尺度变换参数,根据估计参数对水印图像进行相应恢复及水印提取,检测过程不需要原始图像;给出利用原始图像的几何矩和Tchebichef 矩进行估计参数的方法。实验表明,该方法精度高,对水印测试软件Stirmark 具有很好的鲁棒性。
Abstract:
A new scheme of rotation, translation and scaling invariant second generation image watermarking was proposed in this paper. Before dectecting watermark, the parameters of geometric distortions, such as rotation, translation and scaling, were estimated by using the moments of original image, i.e. Geometric moments and Tchebichef moments. The watermark was generated from the original image, which was not required during the detection process. Various simulation results have shown that the proposed method is robust against the popular watermark benchmark-Stirmark.
