New method uses SAM 3 for surgical landmark localization

By PulseAugur Editorial · [1 sources] ·

Researchers have developed a new method for localizing functional landmarks in surgical videos by leveraging the Segment Anything Model 3 (SAM 3). This approach uses SAM 3's structural prior to provide dense instrument-level context without requiring manual pixel-level annotations. A coarse multi-frame network generates prompts that refine SAM 3's output, leading to improved predictions for tip and anchor localization. Experiments on a dataset of 7,867 clips from 60 surgical videos demonstrated F1 scores of 72.4% for tip and 58.0% for anchor localization. AI

IMPACT This research could improve the precision of surgical navigation systems by enabling more accurate identification of critical surgical points.

    Dense Structural Priors for Sparse Functional Landmark Localization in Surgical Videos

    arXiv:2606.31007v2 Announce Type: replace Abstract: Vision foundation models such as SAM 3 can provide transferable object-level structure across diverse surgical video conditions, but segmentation outputs do not explicitly encode the action-conditioned semantics that define func…
