Efficient computation reduction algorithms for frame rate up-conversion

This paper proposes two novel frame rate up-conversion (FRUC) algorithms including motion vector smoothing and hole interpolation using intra prediction. The proposed algorithms can efficiently reduce the degradation of interpolated frames by removing blocking artifacts and blurring. Experimental results show that the proposed algorithms improve the average PSNR of the interpolated frames by 4.15dB compared to the conventional algorithm using bilateral motion estimation (ME), while it shows an average 0.16dB lower PSNR performance than the existing algorithm using unilateral ME. However, the proposed FRUC algorithms can significantly reduce the computational complexity based on the absolute difference by 47.3%.
