| 摘 要： | 论文给出了一种新的基于小波变换和图像置乱的水印算法。先将要嵌入到数字产品中的数字水印图象进行置乱,然后用基于小波域的算法将其嵌入到数字产品中。这样可以有效地抵抗裁减攻击,并且对提取的水印图像,可以使用确定噪声点的滤波算法进行改善,试验效果令人满意。

| Abstract: | In recent years,digital watermarking has been widely used in copyright protection for digital images.The paper gives a new watermark algorithm based on wavelet transform and scrambling.Firstly,it introduces how to realize digital image scrambling.Secondly,a method of embedding the watermark in digital images base d on the discrete wavelet transform is proposed.Moreover,experimental results have proved that the method is robust enough to some image degradation process such as cropping and sharpening etc.The simulation results are shown. |
