Frame rate up-conversion with nonlinear temporal interpolation

Motion compensated frame rate up-conversion (MCFRUC) partly resolves some of the issues in video interpolation such as blurred images resulting from incorrect linear motion interpolation and motion jerkiness caused by frame repetition. Most of the block artifacts and incorrect interpolated frames are caused by linear-motion-based FRUC. In this paper, we evaluated a motion-compensation approach based on nonlinear spatio-temporal motion assumption which is more general and realistic than linear assumption. New motion model is tested against linear counterpart, proving clear superiority in generating better reconstructed and closer to the ground truth intermediate frames.
