This is a PyTorch implementation of a semi-supervised learning framework for building damage assessment. The manuscript can be visited via https://www.mdpi.com/2072-4292/15/2/478.

You need to first generate lists of pre- and post-image/label files and place as the structure shown below. Every txt file contains the full absolute path of the files, each file per line. To ensure you can understand what are the files, we give three tif files as examples. The image file is the RGB-band file and label file is the 256-bit image with value from 0 to 255.

/root
    /train_image_pre.txt
    /train_image_post.txt
    /train_label.txt
    /test_image_pre.txt
    /test_image_post.txt
    /test_label.txt
    /val_image_pre.txt
    /val_image_post.txt
    /val_label.txt
    /train_unsup_image_pre.txt
    /train_unsup_image_post.txt

The code is developed using Python 3.7 with PyTorch 1.9.1. The code is developed and tested using singel RTX 2080 Ti GPU.
