Image Scrambling Effect Evaluation Method Based on Position Correlation
Xingrong Zhong · Jisuanji gongcheng · 2010
By using Euclidean distance norm to describe position correlation of image pixels,a novel image scrambling effect evaluation method is proposed in this paper.It evaluates image scrambling effect of image encrypted by two scrambling algorithms such as Arnold transform and M-sequence transform.Experimental results show that the proposed method is effective to describe the relation of the image scrambling effect and the number of scrambling.It is in accordance with the subjective evaluation results.
