Motion Correction for Thermography using Co-registered Visual-Light Images

Motion correction for intraoperative thermography is a great challenge. Both motion and physiological processes, such as heat transfer due to brain activity, are manifested in temperature variations. To unambiguously detect and correct motion, we employ co-registered visual-light images. Complementing our previous work, we propose a complete workflow and verify the methods by analysing breath and pulse frequencies before and after motion correction. Our approach is able to accurately correct motion without affecting physiological temperature shifts.
