Abstract

PURPOSE: Achieving fine-grained understanding of surgical gestures remains a fundamental challenge in computer vision, due to the subtle and temporally overlapping nature of surgical motions. Gesture boundaries, where transitions between surgical actions occur, present challenges for precise temporal localization. We propose a temporal boundary analysis framework that improves overall surgical ges…
