Detection and compensation of relative motion in endoscopic heart valve recordings by circular Hough transform

By S. König, M. Kondruweit, M. Weyand, T. Wittenberg and S. Friedl


Endoscopic video recordings are regularly used to analyze movements of heart valves [1-3]. Due to the recording setup, non-predictable relative motion between optics and valves leads to difficulties while interpreting and comparing results [4]. A detection and compensation of this relative motion is a necessary step prior further analysis. A major challenge here is to distinguish between relative motion and the valve movements. In this contribution, an approach for motion detection based on a circular Hough-transform is presented which exploits the given anatomical structure
