| 摘 要： | 在对图像置乱效果定性评价分析的基础上提出了位置、灰度和偏差度是衡量置乱效果的重要因素,并应用数学建模的方法对各因素的影响程度进行了量化,从而给出新的图像置乱度公式.实验表明,该置乱度公式可有效衡量图像置乱程度的效果,与人的直观视觉效果较为吻合.

| Abstract: | With the wide use of image scrambling technology, how to quantify the effect of image scrambling evaluation has become a widespread concern. Based on the qualitative analysis, this paper states that location, gray and deviation are important factors of measuring scrambling effects. It applies the method of mathematical model to quantify the influence of each factor and gives a new formula of image scrambling. Experimental resuits show that the formula can effectively measure the degree of image scrambling and tallies with people＇s direct viewing visual effect. |
