A Low Complex Selective Block Correlation for Video Frame Interpolation

Abstract

This paper presents a new frame interpolation technique based on correlation between non overlapping macro blocks. The proposed algorithm generates correlation values and identifies the median value as threshold amongst them. The blocks with correlation less than threshold are linearly interpolated. By linear interpolation between blocks reduces artifacts due to occlusions and holes caused by Motion Vector (MV) processing. Our algorithm decreases the computational complexity to minimum. Experimental results demonstrate that our proposed algorithm performs well in terms of SSIM and computational complexity compared to existing  algorithms.
