| 摘 要： | 为有效提取边缘密度大的遥感图像中的边缘信息，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像的噪声，然后将二值图像的边缘提取算法推广到灰度图像中加以应用。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。

| Abstract: | In this paper, we introduce a mathematical morphological algorithm for edge detection in remotely sensed images of high density edges. Firstly, we filter the noise by using open-closing morphology filter, then use an edge detection algorithm derived from binary mathematical morphology. The experiment proves that this algorithm is more effective than Morphological gradient algorithm and Canny algorithm. |
