居民地是遥感影像中重要的地形要素之一,在研究居民地影像特征的基础上,提出一种基于形态学开闭运算的居民地边缘检测算法。试验结果表明,该方法能很好地检测出居民地的边缘。
Residents’ land is one of the most important terrain features in remote sensing images. Based on the study of resident image features, this paper proposes a resident edge detection algorithm based on morphological opening and closing operations. The test results show that this method can detect the edge of residential area well.
