| 摘 要： | 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.

| Abstract: | 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... |
