Overview of SARAS-Net:

Visualize each module by Gradcam:

cuda: 11.0  
python: 3.6.9  
pytorch: 1.7.0  
torchvision: 0.8.1 

git clone https://github.com/f64051041/SARAS-Net.git  
cd SARAS-Net  

Download LEVIR-CD weight : https://drive.google.com/file/d/1Gs6iYQcZI1Jm4NhthCwWI2olbO-bpvTd/view?usp=share_link
After downloaded the model weight, you can put it in SARAS-Net/.
Then, run a demo to get started as follows:

python demo.py

After that, you can find the prediction results in SARAS-Net/samples/

You can find SARAS-Net/cfgs/config.py to set the training parameter.

python train.py

After training, you can put weight in SARAS-Net/.
Then, run a cal_acc.py to get started as follows:

python cal_acc.py

You can set show_result = True in cal_acc.py to show the result for each pairs.
