基于二维混沌映射的数字图像置乱方法

Digital image disorder based on a two-demensions chaos map

利用混沌系统中的二维Sinai映射 ,采用两组初始参数不同的混沌映射来产生两组不同的伪随机的混沌时间序列 ,基于混沌映射伪随机性优良特性 ,并针对数字图像的特点进行随机空间置乱操作实验 。

The paper uses two-dimensions Sinai map of chaos system. Two group different original parameter′s chaos map produce two group different stochastic chaos time sequence.Because chaos map′s specialty is first-rate randomicity, we use it in digital image disorder experiments of random space, and effect is preferable.This program is compiled by VC++.
