SAR and Optical Image Registration Based on Uniform Feature Points Extraction and Consistency Gradient Calculation
Synthetic aperture radar (SAR) satellites have an active sensor on board, which emits electromagnetic signals and measures the strength and time delay of the returned signal backscattered from ground objects. Optical images have rich spectral information, but it is easily affected by atmospheric att...
