摘要:We propose a frame rate up-conversion method with quadruple motion vector post-processing scheme (QMVPS). By considering occlusion and hole problems, we adopt the hybrid motion estimation ( ME) method which is a combination of bilateral ME and unilateral ME in both directions. To produce better quality-interpolated frames, the motion vector (MV) outliers of the both unilateral MV fields are detected and corrected by prior-information-based MV refining method and the bilateral MV field is smoothed by using vector extrapolation and weighted summation. Moreover, the selection and determination criterion, which is composed of matching ratio of blocks and ladder-style analysis, is proposed to select and decide the denser bilateral MV field. Experimental results verify the superiority of our work in both objective and subjective performances compared with other conventional ME and MV post-processing methods.
