| 摘 要： | 提出了一种从SAR影像的多个极化通道探测道路的新方法。首先，介绍了用边缘探测器构造道路探测器的方法； 然后，将多参数统计假设检验的方法应用到全极化影像的信息融合中，并将该方法提取的结果与传统Tupin法提取的结果进行了比较。实验表明，该方法对全极化SAR影像道路边缘的提取效果较好，具有一定的适用性。

| Abstract: | A new method for detection of roads in multi - channel polarimetric SAR images is proposed in this paper. The technology for construction of the road detector from edge detectors was described, the approach based on multivariate statistical hypothesis tests was applied to information fusion of SAR images, and the extracting result from two traditional Tupin methods and that from the method proposed in this paper were compared with each other. Experiments show that the method proposed in this paper, when applied to detecting roads on a full - polarimetric SAR image, can yield relatively satisfactory result. |
