基于改进SUSAN算子的图像边缘检测算法

首先介绍了SUSAN边缘检测算子的原理;然后对算法中灰度差阈值的选择方式进行了改进,采用一种自适应选取阈值的方法取代算法中人为的设定阈值,使其在各种不同对比度的图像中都能正确提取出图像边缘;最后运用该算法进行了图像边缘检测测试,并与其他检测算子进行比较.实验结果表明,该算法具有方法简单、抗噪能力强、计算量小等优点.

Image Edge Detection Algorithm Based on Improved SUSAN Operator

SUSAN edge detecting operator is an edge detection algorithm based on comparison of the image gray.First,this article introduces the principle of the operator;then it improves the gray threshold using an adaptive threshold method instead of the one of artificial hypothesis threshold value,which extracts edge correctly in different contrast image;finally,the algorithm is used to test two images and compare them with other detection operators.The results show that the algorithm has traits such as simple metho...
