Area of Science:

  • Robotics
  • Computer Vision
  • Medical Imaging

Background:

  • Robotic assistance in retinal microsurgery requires precise visual tracking of surgical instruments.
  • Existing tracking methods struggle with the dynamic and complex appearance changes of instruments in in-vivo surgical videos.

Purpose of the Study:

  • To develop a novel, robust, and data-driven visual tracking approach for surgical instruments in retinal microsurgery.
  • To improve the accuracy and reliability of instrument tracking in challenging in-vivo environments.

Main Methods:

  • A novel pipeline integrating a learned, data-driven detector with a traditional gradient-based tracker.
  • Development and utilization of a fully annotated dataset of retinal instruments from in-vivo surgeries for quantitative validation.
