This is the official code for the NWD. The expanded method is received by the ISPRS JP & RS in 2022.
You can refer to MMDetection to install and run this project.
mmcv-aitod needs to be installed for replacing official mmcv. cocoapi-aitod can be used to evaluate performance on AI-TOD.
The NWD's config files are in configs/aitod.
