This repository contains code related to the implementation of the 3 deep learning CNNs (Fusion-PNN-Siamese, Fusion-ResNet, Fusion-GAN) which were created in order to fuse Sentinel-2 (20 m) and Worldview images (4 m), as analyzed in the paper cited below.

Run:
"training_preprocessing.py" to apply pre-processing to the training input and output files.
"training.py" to train each model.
"inference_preprocessing.py" to apply pre-processing to the inference input files.
"inference.py" to create the fused image.
"remove_01_scaling.py" to create uint16 values.
"remove_histogram_clipping.py" to remove the histogram clipping effect.
Detailed guidelines are included inside each script.
