The utilization of scale invariant feature transform algorithm in synthetic-aperture radar images (SAR-SIFT) to match image features may lead to principal orientation assignments of descriptors being affected by speckle noise, thereby diminishing accuracy. In this study, we propose using the Fourier histogram of oriented ratio gradient (Fourier HORG) descriptor for robust matching of SAR images. This method is based on the SAR-SIFT algorithm framework. During feature description, the rotation-in ...[more]
