Efficient motion-compensated frame interpolation for high resolution videos using hierarchical motion estimation계층적 움직임 추정을 이용한 고해상도 비디오용 움직임 보상 프레임 보간 기법
Motion estimation (ME) and occlusion handling are important processes for motion-compensated frame interpolation (MCFI) because they influence the quality of an intermediate frame. This paper proposes an MCFI method using hierarchical ME composed of a modified 3-D recursive search. In addition, an adaptive frame interpolation method is proposed by grouping MVs, refining MVs and detecting blocks in occluded regions. The experiment results show that the proposed method outperforms the other MCFI methods in terms of the quality of the intermediate frames.
