  In this paper, we propose a novel motion-compensated frame rate up-conversion
(MC-FRUC) algorithm. The proposed algorithm creates interpolated frames by
first estimating motion vectors using unilateral (jointing forward and
backward) and bilateral motion estimation. Then motion vectors are combined
based on adaptive threshold, in order to creates high-quality interpolated
frames and reduce block artifacts. Since motion-compensated frame interpolation
along unilateral motion trajectories yields holes, a new algorithm is
introduced to resolve this problem. The experimental results show that the
quality of the interpolated frames using the proposed algorithm is much higher
than the existing algorithms.
