Satellite Image Time Series Semantic Change Detection: Novel Architecture and Analysis of Domain Shift
Elliot Vincent Jean Ponce Mathieu Aubry
Official PyTorch implementation of Satellite Image Time Series Semantic Change Detection: Novel Architecture and Analysis of Domain Shift. Check out our webpage for other details!
We tackle the satellite image time series semantic change detection (SITS-SCD) task with our multi-temporal version of the UTAE [3]. Our model is able to leverage long range temporal information and provides significant performance boost for this task compared to single- or bi-temporal SCD methods. We evaluate on DynamicEarthNet [1] and MUDS [2] datasets that exhibit global and multi-year coverage using the SCD metrics defined in [1].

git clone git@github.com:ElliotVincent/SitsSCD.git --recursive
We use processed versions of the SITS-SCD datasets DynamicEarthNet [1] and MUDS [2]. Our pre-processing consists in image compression for memory efficiency. You can download the datasets using the code below or by following these links for DynamicEarthNet (7.09G) and MUDS (245M).

This implementation uses PyTorch, PyTorch Lightning and Hydra.
For both datasets, there are two validation and two test loaders, to account for the presence or not of spatial domain shift.
