SAR Image Registration Based on Multifeature Detection and Arborescence Network Matching.

In this letter, a novel synthetic aperture radar (SAR) image registration method, including two operators for feature detection and arborescence network matching (ANM) for feature matching, is proposed. The two operators, namely, SAR scale-invariant feature transform (SIFT) and R-SIFT, can detect corner points and texture points in SAR images, respectively. This process has an advantage of preserv...
