| 摘 要： | 随着图像置乱技术的发展，出现了各种各样的置乱算法，为了更好地衡量这些算法对不同图像的置乱程度，本文利用canny算子的良好特性，在分析现有评价方法特点的基础上，提出了一种新的描述图像置乱程度的评价方法。试验表明该方法与人的主观评价相接近，且结果不受原图像影响。本文采用MATLAB作为研究工具。

| Abstract: | With the development of digital image scrambling techniques,there have appeared a lot of scrambling methods.In order to measure the scrambling degree of these algorithms to different images better,this paper proposes a new method for accessing the image scrambling degree,which utilities the favorable performance of Canny operator by analyzing the existent assessments of image scrambling degree.Experiments show that the method correlates well with subjective assessment and its results are not affected by the original images.The paper uses MATLAB as the research tool. |
