| 摘 要： | 遥感影像线状目标(主要是指道路)的提取是一个经典研究项目。本文首先基于相位编组的思想,确定出若干个局部图像的主方向,再利用对应方向的Sobel算子进行检测,最后对所得结果进行细化。实验证明,该方法对于图像中弱边界的识别是很有效的。 |

| Abstract: | The detecting of remote sensing image(mainly roads) is a classical research project.This paper first,based on the idea of phase-grouping,fixes the main direction of some local images,then makes detection by using the Sobel detector of the corresponding direction,and finally thins the results.Justified by experiments,this method is effective for the identification of the weak edge in the image. |
| Keywords: | remote sensing image linear object feature extraction phase-grouping |
