Infrastructure Damage Assessment

This is a demo for infrastructure damage assessment using satellite images. It contains two models: one for localization and the other for change detection. The localization model is used to segment the image into three classes: background (in black), road (in grey), and houses (in red). The change detection model is used to detect changes between two images. The output of the change detection model is colored as follows: no change (in black), minor change (in green), major change (in yellow), and destroyed (in red). The output of the localization model (on the left) is blended with the pre-disaster image to highlight the areas of interest. The output of the change detection model (on the right) is blended with the post-disaster image to highlight the changes. You can upload your own images or use the sample images provided below.

Note: the models run at half resolution for faster inference, so the output images will be less accurate than the full-resolution models. It still takes a few minutes to run the inference, so please be patient.
