Medical Image Spatial Grounding with Semantic Sampling
MICCAI 2026 presentation on MIS-Ground, a factorial benchmark that isolates the language-side brittleness behind 3D medical spatial grounding, and MIS-SemSam, a training-free semantic-sampling decode rule that lifts Qwen3-VL-32B by 13.06% to 66.5% overall, the best open-weights result and above Gemini 3 Flash.
