Official implementation of "LSNet: Extremely lightweight Siamese Network for Change Detection in Remote Sensing Images". arxiv|IGARSS2022

We use python/pytorch/torchvision versions as follow:

• python 3.7
• pytorch 1.10.0
• torchvision 0.11.1

You can try a lower version, but the python version is no less than 3.6 and the pytorch version is not less than 1.5. If you have any questions, please submit issue.

We use CDD dataset from Change Detection in Remote Sensing Images Using Conditional Adversarial Networks

For training, you can modify parameters in "metadata.json", or just keep the default and:

python train.py

All the pre-trained models have been upload in ./weights, you can modify "model name" in "metadata.json" and

python eval.py

Noted that the source code has been reconstructed and the results are a little different from the paper. But still keeping efficient.
