AbstractIn this paper, a new frame interpolation method with pixel-level motion vector field (MVF) is proposed. Given that existing methods cannot handle occlusions and blocking artifacts well, there are three contributions in our method: (i) applying the pixel-level motion vectors (MVs) estimated by optical flow algorithm to eliminate blocking artifacts (ii) motion post-processing to keep spatial consistency (iii) robust warping method to address collisions and holes caused by occlusions. The method could remove blocking artifacts and alleviate the artifacts caused by occlusions. Experimental results show that the proposed method outperforms existing methods both in terms of objective and subjective performances, especially for sequences with complex motions. ? 2014 IEEE.
