Motion compensation based multiple inter frame interpolation

In this paper, a fast forward motion estimation (FFME) algorithm based on motion compensated frame rate up-conversion (MC-FRUC) with reduced time complexity is proposed. The proposed algorithm exploits the spatial correlation of the displacement vectors of the neighboring blocks in a frame. The algorithm achieves a reduction in the computational complexity by 85% compared to the existing single frame interpolation scheme, while maintaining almost the same objective quality. A multiple interpolation technique is also presented based on the proposed FFME technique. The experimental results demonstrate the suitability of the method for frame rate up conversion.
