ChangeMamba: Remote Sensing Change Detection with Spatio-Temporal State Space Model

1 code implementation4 Apr 2024 Hongruixuan Chen, Jian Song, Chengxi Han, Junshi Xia, Naoto Yokoya

For the change decoder, which is available in all three architectures, we propose three spatio-temporal relationship modeling mechanisms, which can be naturally combined with the Mamba architecture and fully utilize its attribute to achieve spatio-temporal interaction of multi-temporal features, thereby obtaining accurate change information.
