The official code repository for the paper "Revisiting the Encoding of Satellite Image Time Series".
The preprint is under review.The codebase is still under construction and therefore is subject to further modifications.- The paper has been accepted to BMVC 2023 as an oral presentation.
- The model weights have been made available on Zenodo.
- The slides and the accompanying video, from which you can gain a better intuitive understanding of the development philosophy, can be accessed via the following link.
I have been focusing on expanding this work to a journal paper and the code is subject to further modifications.- I look forward to collaboration to upgrade the code repo (e.g., having it integrated to the Hugging Face Ecosystem) and extend this work to a full journal paper.
Navigating the Repo with DeepWiki (powered by Devin.ai)
A useful document generated by DeepWiki can facilitate you navigating the repo, which is pretty amazing. The following two figures are copied from the DeepWiki document, highlighting the critical implementations.

| Model Name | SQ | RQ | PQ | #Params (M) | FLOPs |
|---|---|---|---|---|---|
| UConvLSTM+PaPs | 80.2 | 43.9 | 35.6 | 2.50 | 55G |
| U-TAE+PaPs | 81.5 | 53.2 | 43.8 | 1.26 | 47G |
| Exchanger+Unet+PaPs | 80.3 | 58.9 | 47.8 | 9.99 | 301G |
| Exchanger+Mask2Former | 84.6 | 61.6 | 52.6 | 24.63 | 332G |
- The panoptic segmentation model Exchanger+Mask2Former has been trained by splitting the input into four 64x64 patches and stitch the prediction results together. Later on, I found this trick is crucial for replicating the results.
