CloudSEN12

This package contains minimum code to run the CloudSEN12 models proposed in Aybar et al. 2022 and Aybar et al. 2024. The main dependencies of this package are pytorch and the georeader package which only depends on rasterio and geopandas libraries.

The notebook run_in_gee_image.ipynb has an example of running the model on a Sentinel-2 image downloaded from the Google Earth Engine:

For examples about dataset use and training see cloudsen12.github.io.

models

With this package, the following models can be loaded: (with the function cloudsen12.load_model_by_name())

• cloudsen12 Model trained on the 13 bands of Sentinel-2 L1C in the CloudSEN12 dataset.
• cloudsen12l2a Model trained on the 12 bands of Sentinel-2 L2A in the CloudSEN12 dataset.
• dtacs4bands Model trained on the NIR, RED, GREEN and BLUE bands of Sentinel-2 L1C in the CloudSEN12 dataset. Bands: ["B08", "B04", "B03", "B02"]
• landsat30 Model trained on the common bands of Sentinel-2 L1C and Landsat 8 and 9 in the CloudSEN12 dataset. Bands: ['B01', 'B02', 'B03', 'B04', 'B08', 'B10', 'B11', 'B12'].
• UNetMobV2_V1 Model trained on the 13 bands of Sentinel-2 L1C in the CloudSEN12 dataset. The cloud masks of this model are included in CloudSEN12+ dataset.
• UNetMobV2_V2 Model trained on the 13 bands of Sentinel-2 L1C in the CloudSEN12+.
