Ship detection and identification in SDGSAT-1 glimmer images based on the glimmer YOLO model
International Journal of Digital Earth, 2023 ABSTRACTRemote sensing technology has been widely used for marine monitoring. However, due to the limitations of sensor technologies and data sources, effective monitoring of marine ships at night remains challenging. To address these challenges, our study developed SDGST, a high-resolution glimmer marine ship dataset from SDGSAT-1 satellite and ...
