摘要: 合成孔徑雷達(dá)(SAR)圖像的匹配處理是SAR圖像后處理及應(yīng)用的重要環(huán)節(jié)。該文提出了一種基于圖像特征的快速匹配實現(xiàn)方法。針對兩幅SAR圖像,該方法進(jìn)行邊緣檢測和區(qū)域輪廓提取以及區(qū)域特征描述,最后實現(xiàn)圖像的自動匹配。利用真實SAR圖像進(jìn)行了試驗,獲得很好的試驗結(jié)果。

Abstract: 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. -
