一种SAR图像的自动匹配算法及实现

Image Matching Algorithm and Implementation for SAR Images

合成孔径雷达(SAR)图像的匹配处理是SAR图像后处理及应用的重要环节。该文提出了一种基于图像特征的快速匹配实现方法。针对两幅SAR图像,该方法进行边缘检测和区域轮廓提取以及区域特征描述,最后实现图像的自动匹配。利用真实SAR图像进行了试验,获得很好的试验结果。

SAR image matching is important to SAR applications. This paper presents a method to fast match SAR images based on image feature. Edge detection and image segmentation are carried out firstly. Then image matching is performed based on the feature of segmented image. The test carried out with real SAR images has achieved good results.
