Cloud Removal with Fusion of High Resolution Optical and SAR Images Using Generative Adversarial Networks

no code implementations MDPI Remote Sensing 2020 Jianhao Gao, Qiangqiang Yuan, Jie Li, Hai Zhang, Xin Su

The approach can be roughly divided into two steps: in the first step, a specially designed convolutional neural network (CNN) translates the synthetic aperture radar (SAR) images into simulated optical images in an object-to-object manner; in the second step, the simulated optical image, together with the SAR image and the optical image corrupted by clouds, is fused to reconstruct the corrupted area by a generative adversarial network (GAN) with a particular loss function.
