| 摘 要： | 提出了一种基于模糊算子理论的道路半自动提取方法。该方法在对小比例尺影像进行Sobel边缘检测的基础上，定义了12种模糊算子表示2维道路的各种可能的结构，然后在给定道路种子点附近形成的一定范围内进行搜索，提取出道路的中心线。实验结果表明，该算法速度较快并且具有较强的鲁棒性。

| Abstract: | This paper presents a new approach of semi-automatic road extraction based on the fuzzy mask concept. In this approach, a set of twelve fuzzy sets representing basic 2D road structure is defined. Sobel edge-detection is used at first to get the edge-image from a low-resolution satelllite image; then the road axis is extracted in the scale which is limited by a pair of seed points given by the operator. Obtained results indicate that this approach is fairly fast and robust. |
