摘　　要：信息隐藏是遥感影像信息交换环节中必不可少的步骤.提出一种基于多层感知机的可逆信息隐藏算法,先对原始影像和载体影像进行拆分和排序,形成映射并组成样本,再将样本交付预先搭建好的感知机进行训练,最后把训练生成的权值文件作为数字水印嵌入载体影像.实验表明,该算法不可感知性高,鲁棒性强,影像提取速度快,精度比主流算法高13%左右.It is a necessary step to hide information in the process of remote sensing images information interaction.A reversible information hiding algorithm based on multi-layer perceptron is proposed.Firstly,the algorithm cuts and disrupts the original remote sensing image and the carrier images,forms a map,and gets samples.Secondly,the samples are sent to the prepared perceptron for training.Finally,the generated weight file is embedded in the carrier images as digital watermarks.The experiment shows that the algorithm is nearly unperceivable and robust.The speed of information extraction is fast,and the accuracy of information extraction is about 13%higher than that of the mainstream algorithm.
