Feature Matching for SAR and Optical Images Based on Gaussian-Gamma-shaped Edge Strength Map

Feature Matching for SAR and Optical Images Based on Gaussian-Gamma-shaped Edge Strength Map

A matching method for SAR and optical images, robust to pixel noise and nonlinear grayscale differences, is presented. Firstly, a rough correction to eliminate rotation and scale change between images is performed. Secondly, features robust to speckle noise of SAR image are detected by improving the...
