摘要
该文实现了基于LSB算法的遥感影像的水印嵌入和提取,对嵌入水印的图像进行了几种常见的攻击测试,并对实验结果进行了分析。实验证明LSB算法具有较高的水印不可见性,易于实现,对高斯噪声、椒盐噪声和旋转等攻击具有一定的鲁棒性。
In this paper, the embedding-watermark and extracted-watermark algorithms on a remote sensing image are implement-ed based on LSB. Some familiar attack tests are applied in the image that have embedded watermark, and the results are analyzed.Experiments have shown that the LSB algorithm proposed in this paper has good invisibility, easy realization. And it has a certainrobustness against Gaussian noise, impulse noise, rotation attacking, etc.
