UniRef-UAV (Image-only): leaderboard
UniRef-UAV is a referring benchmark for drone imagery in which a query may name no target, one target or several, and the model must return exactly the matching set of boxes. This board uses image-only queries, restricted to existence-aware single-instance grounding. A query counts as correct only when the predicted boxes match the annotated set one to one at an intersection over union of at least 0.5, and an empty prediction is correct only when there is no target.
Metric: Precision@(F1=1, IoU>=0.5) (%; share of the image-only (existence-aware single-instance) test queries whose predicted box set exactly matches the referred target set under one-to-one IoU>=0.5 matching, an empty prediction being correct only for no-target queries; zero-shot, model-specific grounding prompt, unparseable output read as an empty prediction). Source: arxiv.org. Saturation forecast: Around March 2027. 13 models tracked.
