Sentinel-2 Sharpening Using A Single Unsupervised Convolutional Neural Network With MTF-based Degradation Model
2021
IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing
The Sentinel-2 (S2) constellation provides multispectral images at 10 m, 20 m, and 60 m resolution bands. Obtaining all bands at 10 m resolution would benefit many applications. Recently, many model-based and deep learning (DL)-based sharpening methods have been proposed. However, the downside of those methods is that the DL-based methods need to be trained separately for the 20 m and the 60 m bands in a supervised manner at reduced resolution, while the model-based methods heavily depend on
