An evaluation method of image scrambling degree based on correlation
Yuanzhi Wang · Information technology newsletter · 2008
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.
