摘要
指出一般的图像域信息隐藏算法并不适用于遥感影像,并将信息隐藏的涵义加以拓广,提出了基于影像融合的遥感影像授权使用小波域算法,该算法能根据用户的权限不同程度地隐藏遥感影像中的机密信息,是基于HVS特性的自适应于遥感影像特征的盲算法.
In this paper, we illuminated that general image hiding algorithms do not adapt to remote sensing image, and therefore, we extend the connotation of information hiding and proposed a wavelet algorithm for authorized exploitation of remote sensing image based on image fusion. The algorithm proposed in the paper can hide the secrets in a remote sensing image to various degrees according to users＇ authorizations at various level. Therefore, is in practice blind information hiding algorithm adaptable to characters of a remote sensing image based on HVS character.
