Interactive feature fusion method and device for remote sensing image change detection

The invention discloses an interactive feature fusion method and device for remote sensing image change detection, and relates to the field of remote sensing image change detection. Feature information of different scales is extracted through different convolutional layers; the extracted features are rearranged, each group of features after rearrangement covers different scales, and global cross-scale feature interactive attention fusion is carried out on each group of features with different scales after rearrangement; spatial interactive attention fusion and dimensional interactive attention fusion are performed on the two feature groups interacted at different times, the spatial interactive attention fusion focuses on capturing position information in dual-time features and improving overall expressive force and generalization ability, and the dimensional interactive attention fusion emphasizes important dimensions and highlights importance and expression ability of the features; performing non-local inter
