Enhanced Frame Rate Up-Conversion Method for UHD Video

Abstract

In this paper, a segment-based motion estimation (ME) method for frame rate up-conversion is proposed that can achieve better visual quality for next generation video formats. The proposed ME method can reduce the computational complexity of the ME drastically by adjusting the search range (SR) for each segment and adopting a new efficient distortion criterion, called the sub-sampled sum of absolute differences (SSAD). The proposed method does not degrade the motion accuracy by using the temporal consistency of the segment with large size. Experimental results show that the proposed algorithm outperforms conventional methods both objectively and subjectively with the significantly reduced computational complexity(1).
