RefineRank: Joint Box Refinement and Ranking for Surgical Spatio-Temporal Grounding

arXiv · AI, language, vision and robotics · article · Aug 25, 2026 · UTC

Surgical spatio-temporal grounding (STG) requires locating, at each video time specified by a procedural question, the object that the question asks about. Existing approaches face a trade-off: vision language models understand the question context but produce imprecise coordinates, whereas open-set detectors provide localized candidate boxes whose confidence does not reflect which box answers the question. We introduce RefineRank, which closes this gap at the candidate-box level. A compact trainable module, RefineNet, combines the language and regional features of a frozen medical vision lang
