In the information hiding algorithms based on digital images, it is very important to evaluate the image scrambling degree. 摘要在基于数字图像的信息隐藏算法中，如何评价图像置乱程度是一个很重要的问题。
By contrast with the experimental results of other algorithms, it shows that the algorithm has a better image scrambling effect and could reach the purposes of image scrambling. 通过与其他算法的实验对比，表明该算法有较好的图像置乱效果，达到了对图像进行置乱的目的。
