摘要
以约瑟夫遍历、位置置乱和灰度置乱为基础,提出了一种基于约瑟夫遍历的数字图像置乱方法,该方法简单易行,置乱效果良好,可用作信息隐藏与伪装的预处理。
The paper presents a scheme of digital image scrambling based on Josephus traversing,position disordering and gray-level disordering.This method is easy to realize,and has satisfied scrambling effect.It also can be used as pretreatment for digital image hiding and disguising.
