A Novel Method for Frame Rate Up-Conversion
In this paper, we proposed a new motion compensated interpolation (MCI) algorithm for frame rate upconversion (FRUC) in multimedia applications. First, we propose the bilateral motion estimation (ME) scheme to obtain the motion field of an interpolated frame without yielding the hole and overlapping problems. Secondly, we partition the block which the sum of bilateral absolute differences (SBAD) is bigger than a threshold into four sub-blocks and reestimate by bilateral ME. Thirdly, we smoothed the motion vectors (MVs) using spatio-temporal motion vector smoothing (MVS). Finally, we use the overlapped block motion compensation to generate interpolated frames and further reduce block artifacts. Experimental results show that the proposed algorithm provides a better image quality than conventional methods both objectively and subjectively.
