Popis: Deep-learning-based broad area damage/change assessment (BADA) monitors environmental change due to disaster damage. Our approach was developed while competing in the xView2 challenge. The purpose of the xView2 challenge was to provide a capability to aid humanitarian relief efforts in response to a natural disaster. Given a pre-disaster and a post-disaster image (satellite EO), the goal of the challenge was to locate structures in the imagery and, on a per-structure basis, apply a damage level classification: no damage, minor damage, major damage, or destroyed. We extend the xBD dataset [1], [2], which is the dataset used for the xVeiw2 challenge, using a nearest neighbor label transfer and a distance-based confidence weighting, to allow our Siamese U-net to both predict damage levels at every pixel in the image and, combined with a U-net for building segmentation, provide damage assessment to individual buildings.
