Initial Assessment Of Facial Nerve Paralysis Based On Motion Analysis Using An Optical Flow Method by Sundaraj, Kenneth, W. Samsudin, Wan Syahirah, Ahmad, Amirozi, Salleh, Hasriah

“…An initial assessment method that can classify as well as categorize the severity of paralysis into one of six levels according to the House-Brackmann (HB) system based on facial landmarks motion using an Optical Flow (OF) algorithm is proposed.The desired landmarks were obtained from the video recordings of 5 normal and 3 Bell’s Palsy subjects and tracked using the Kanade-Lucas-Tomasi (KLT) method.A new scoring system based on the motion analysis using area measurement is proposed.This scoring system uses the individual scores from the facial exercises and grades the paralysis based on the HB system.The proposed method has obtained promising results and may play a pivotal role towards improved rehabilitation programs for patients.…”

Extract Motion from Picture Sequence by MOHD SHAFIQ AHMAD DAHALAN, MOHD SHAFIQ

“…Motion is represented as vectors at every pixel in a digital image sequence of two frames which are taken at time t and t + δt respectively. Based on the assumption of the observed brightness (intensity) of any object point is constant over time interval and the movement is small, optical flow equation (OFE) is derived and used in algorithm to calculate optical flow for a particular motion. …”
