Fast FFT-based motion compensation for laryngeal high-speed videoendoscopy

Szymon Cieciwa, Dimitar D. Deliyski, Tomasz P. Zielinski

Six methods for endoscopic motion compensation for laryngeal high-speed videoendoscopy (HSV) are compared. Two of them are based on tracking the maximum of the cross-correlation function of two images; two are based on minimization of the L2–norm and L2-like distance between two images; and the other two make use of the peak present in the cross-power FFT-based spectrum of two images. All six methods are applied to compensate the motion, at the sub-pixel level, of the endoscopic lens relative to the vocal folds in HSV recordings. The new motion compensation methods based on FFT cross-power spectrum demonstrated remarkable computational speed and acceptable accuracy. While accuracy was best for the L2-minimization techniques, they were slower and had a limited motiontracking range.
