PLEASE BE AWARE THAT THIS REPO IS CURRENTLY UNDER MAINTENANCE, WE ARE UPGRADING THE CODE A NEWER IMPLEMENTATION WILL APPEAR SOON

The proposed PLFM model combines a time-series of optical images and a SAR image to remove clouds from optical images.

Cloudy Image	Model Prediction	Ground Truth

Usage

To train the PLFM you can simply run

python main.py --train dataset_path

where dataset_path should contain 2 subfolders named "training" and "validation".

To change default parameters please look at models configuration file.

To test the PLFM you can simply run

python main.py --test dataset_path

where dataset_path is the path to the test dataset.

Dataset

The dataset will be available soon.
