摘要
为有效提取边缘密度大的遥感图象中的边缘信息,该文提出了一种利用灰度形态变换原理进行检测的有效算法,首先利用开-闭形态滤波器降低输入图象的噪声,然后将二值图象的边缘提取算法推广到灰度图象中加以应用。实验结果证明,此方法优于灰度形态梯度法,同时也优于Canny算子。
In this paper,we introduce a mathematical morphological algorithm for edge detection in remotely sensed im-ages of high density edges.Firstly,we filter the noise by using open-closing morphology filter,then use an edge detec-tion algorithm derived from binary mathematical morphology.It has been demonstrated that this algorithm do more effec-tively than Morphological gradient algorithm and Canny algorithm.
