Algorithms for Synthetic Aperture Radar Imagery V
We present a fully automatic method for the alignment SAR images, which is capable of precise and robust alignment. A multiresolution SAR image matching metric is first used to automatically determine tie-points, which are then used to perform coarse-to-fine resolution image alignment. A formalism is developed for the automatic determination of tie-point regions that contain sufficiently distinctive structure to provide strong constraints on alignment. The coarse-to-fine procedure for thedoi:10.1117/12.321816 fatcat:zvr7z4ns4fdtlktv3asbvab4za
