| 摘 要： | 本文提出了一种新的SAR图像桥梁检测方法。首先采用单阈值法通过二值化处理分割出河流的主轮廓。在此基础上，对二值图像进行腐蚀和膨胀运算后与河流轮廓图像异或，通过去除边界线检测出桥梁的位置，并在桥梁位置处设置窗口分割出桥梁区域。最后，以Sandia实验室高分辨率SAR图像为样本进行仿真实验，实验结果证明了本文方法的有效性。

| Abstract: | A new approach to detecte bridge in synthetic aperture radar(SAR) image is presented.By using a single threshold method,the rivers are segmented through binarization processing firstly.After dilation and erosion operation to binary image,the results XOR the river outline image,then locations of bridges can be detected by removing boundary lines.Finally the bridges can be segmented by setting windows at the locations of the bridges.Effectiveness of the approach is verified through simulation test by using hi... |
