摘要
提出了一种离散小波(DWT)域数字水印用于遥感图像的机密信息隐藏的算法。仿真实验表明,该算法不仅实现简单具有很强的透明性和大的信息隐藏量,而且对嵌入水印后的遥感图像的自身统计特性及使用价值基本不受影响。
This paper proposes a method of digital watermarking algorithm based on DWT domain for secrete information hiding in remote sensing image. Experimental results show that this algorithm is not only quite transparent and has a good effect for large a- mount of secrete information hiding, but also has little effect for the statistical property and use value of remote sensing image.
