Effective evaluation method of image scrambling degree
Sen Bai · Computer Engineering and Applications Journal · 2009
As the developing of the image scrambling technique,how to evaluate the advantage and disadvantage of scrambling transformation is the hot and difficult issue of research.In order to evaluate the image scrambling degree effectively,the paper gives difinition of the continuity extent.And a new evaluation method of image scrambling degree based on the number of the continuity extent changes when the positon of the pixel changes is provided.The simulation result shows that the method can measure the impact of the every image scrambling phase.
