Twelve epochs of RTMDet-S on the VH chips of OSSDD reached 88.54% AP50 on the held-out test. It found 95.5% of the ships, in 45 minutes. Five ships in a harbor, bright land around the water. RTMDet-S at score 0.3 draws five boxes and matches all five. The same recipe with the other two heads is below.
