| 摘 要： | 为了对数字图像置乱程度进行有效的衡量,根据数字图像相邻点之间像素值的相关性随像素点位置的变化而改变这一原理,提出了一种基于各相邻点之间像素值差异的图像置乱程度衡量新算法.并由Matlab软件仿真结果表明,该方法可以清楚的表现出图像置乱程度与置乱次数的关系.

| Abstract: | In order to evaluate the image scrambling degree effectively, considering the correlation between neighbor points of the digital image, when the points in the image are changed, the correlation will be changed too, a new evaluation arithmetic of image scrambling degree based on the correlation diversity is provided in this paper. The simulation result of Matlab shows that the method can measure the relationship between the times of image scrambling and scrambling degree effectively. |
