Researchers have introduced MariSat, a new dataset designed for instance segmentation of maritime objects in satellite and aerial imagery. The dataset comprises 1260 images annotated at the pixel level for eight distinct maritime object classes. MariSat was developed using a semi-automatic pipeline that combined the Segment Anything Model 3 (SAM 3) with post-processing filters and manual quality control via the CVAT platform. This new resource has already been utilized to fine-tune and benchmark models like SAM 3 and YOLOv11 for real-time maritime surveillance. AI
