| 摘 要： | 对遥感影像中居民地提取的各种方法作了一般性的阐述，并在吸收这些算法优势的同时，提出了一种全自动实现遥感影像中居民地目标的提取方法：先求取非最大值抑制后的梯度图，而后进行高斯模糊处理，以提高影像上居民地区域纹理特征一致性；通过增强大津法和形态学的方法全方位腐蚀与膨胀，完成面状地物居民地的提取；最后进行图象矢量化处理。论述方法的同时，展示和分析了实验结果。

| Abstract: | To remote sensing image for the extraction of residential area of various method made to elaborate gen-erally, and absorbed these calculate ways advantage, at the same time provided a valid one to extract residential characters automatically:Firstly, the grads map which restrained by not max value is calculated; then gauss blur disposing is applied to improve the coherence of the residential area textures on image; By using morphologic method to erode and expand the textures omni directionally to realize the extraction of the area residential and ve-ctors track.; Carry on the portrait vector turns the processing finally. Discussed the method, displayed and anal-yzed the result of the experiment. |
