基于局部统计特征的边缘检测

该文通过分析图像灰度信息的变化,提出局部变异系数的概念,并指出使用该特征进行图像边缘检测的可行性。对于提出的算法,该文结合不同图像进行了实验仿真,并对实验结果进行了分析。由实验结果表明,针对某些图像,使用局部变异系数能较好的提取出图像的边缘。最后,还指出了该算法一些改进的方法。

Local Statistical Character-based Edge Detection

To analysing the information of gray in a picture,the concept-local variation coefficient was proposed in this paper,at the same time,feasibility of this concept which was use for edge detection was pointed out.The experimental results and its analysis were both shown in this paper.The experimental results demonstrate that the method is sutiable for edge extraction of some image.At the last,some disadvantages of this method,in addition,the improvement for it were introduced in this paper.
