Motion estimation with adaptive block size for motion-compensated frame interpolation

This paper proposes a new frame rate up-conversion (FRUC) method. In the paper, we propose an overlap ratio between motion vectors, with which we determine adaptive block size for the motion estimation. In addition, the proposed method estimates the region of repeated patterns and treats them in a s...

Summary:This paper proposes a new frame rate up-conversion (FRUC) method. In the paper, we propose an overlap ratio between motion vectors, with which we determine adaptive block size for the motion estimation. In addition, the proposed method estimates the region of repeated patterns and treats them in a special manner. Conventional motion estimation methods usually produce wrong motion vectors for the repeated patterns. The experimental results show that the proposed method outperforms other FRUC methods in terms of generating better interpolated frames.
