遥感影像局部兴趣目标的可逆信息隐藏算法

提出了一种适用于遥感影像局部兴趣目标授权使用的可逆信息隐藏算法。提取遥感影像上的局部兴趣目标作为待隐藏的信息,并在原始图像上对该目标进行变形处理,然后利用可逆整数线性变换实现待隐藏信息的调制嵌入,授权用户能够完全无损重建原始遥感影像。算法为盲算法,具有较大的嵌入容量,含隐藏信息图像的峰值信噪比较高,并且可以有效抵抗剪切及椒盐噪声等攻击。

Reversible Data Hiding Algorithm for Local Interest Object of Remote Sensing Image

This paper presents a reversible data hiding algorithm for local interest target authorization exploitation of remote sensing image.First,extracting the local interest target in remote sensing image as the information to be hidden,deforming the target on the original image,and then using reversible integer linear transform to modulate the information embedding,the authorized users can reconstruct the lossless original remote sensing image.The algorithm is blind,with a large embedding capacity,the embedded i...
