We hope that STAR will serve as a solid baseline and help ease future research in weakly-supervised object change detection.
News
- 2021/09/24, ChangeStar has been included in microsoft/torchgeo!
- 2021/08/28, The code is available.
- 2021/07/23, The code will be released soon.
- 2021/07/23, This paper is accepted by ICCV 2021.
Features
- Learning a good change detector from single-temporal supervision.
- Strong baselines for bitemporal and single-temporal supervised change detection.
- A clean codebase for weakly-supervised change detection.
- Support both bitemporal and single-temporal supervised settings
