SAAN: Similarity-aware attention flow network for change detection with VHR remote sensing images

no code implementations28 Aug 2023 HaoNan Guo, Xin Su, Chen Wu, Bo Du, Liangpei Zhang

These CD methods, however, still perform far from satisfactorily as we observe that 1) deep encoder layers focus on irrelevant background regions and 2) the models' confidence in the change regions is inconsistent at different decoder stages.
