Residual energy and edge information based motion estimation algorithm for frame interpolation

In this paper, we propose a novel motion estimation algorithm for true motion estimation. After obtaining an initial motion vector map through hierarchical block matching algorithm with distance constraints, we classify the motion vectors based on residual energy map. With block and edge information, the motion vector map can get updated iteratively until it reaches the predefined condition. The experiment results show that the proposed method improves the quality of interpolated frames compared with some recent algorithms.
