October 15, 2026 OSSDD — Sentinel-1 ships, finetuned with RTMDet, Faster R-CNN, and FCOS
OSSDD is Sentinel-1 GRD ship chips with rotated boxes. VH 1× finetunes from the DOTA hubs. Held-out test AP50 at IoU 0.5 and score 0.3: RTMDet-S 88.54%, Rotated Faster R-CNN 70.53%, Rotated FCOS 52.70%. The paper mAP on these rotated boxes is 69.09% / 60.10% / 62.65%. No OSSDD Hub.
