Abstract

This work presents a methodology for the development of regularized optical flow computation methods for video. The proposed methodology is based on a discrete formulation of the optical flow problem. The optical flow computation methods produced by the proposed methodology are utilized to extract temporal motion strength signals from video recordings of neonatal seizures.
