In this paper, a new motion compensated frame interpolation method is proposed based on the reliability of motion vectors determined by the block residual energy. Additional motion re-estimation is applied to those blocks where unreliable motion vectors are detected. The motion estimation algorithm employed in this work combines block-based motion estimation with optical flow-based estimation, resulting in a more accurate representation with only modest computational complexity. The experimental results show that it can improve the visual quality of the interpolated frames where competing methods fail.
