PICO: Projection-Informed Consistency Optimisation for 6DoF surgical tool pose estimation.

PURPOSE Accurate 6 DoF pose estimation of surgical tools is critical for automation, robotic proprioception, and safe interaction with the tissue operated on. Kinematics-based approaches suffer from accumulated errors due to the cable-driven nature of robotic arms, while vision-based methods often rely on external mark...

STSG-VQA: Evidence-Grounded Temporal Question Answering from Surgical Spatio-Temporal Scene Graphs

Despite recent advances in surgical vision-language models (VLMs), temporal reasoning remains limited because existing supervision is largely frame-centric. Frame-level scene graphs (SGs) have proven effective in providing structured representations of surgical environments but do not explicitly model the dynamics of s...
