SAR2Opt-Heterogeneous-Dataset

This is an overview of our proposed heterogeneous remote sensing images "SAR2Opt" dataset.

SAR2Opt dataset can be used as a benchmark in change detection and image transaltion on remote sensing images.

Description of dataset

We manually selected ground points on each pair of SAR-optical images to perform fine registration. All the pathces were cropped in size of 600*600 pixels after registration. If you want to use a pre-trained model, you could resize the patches first.

Image-to-image translation results on SAR2Opt dataset

Here are some translated results on our SAR2Opt dataset with well-known GAN-based methods, which have been included in our GRSL paper.

Usage of codes

We slightly modofied the original codes to make our dataset suitable for the models. And we are grateful to the authors who have shared their codes kindly.
