New Motion Estimation with Angular-Distance Median Filter for Frame Interpolation
A novel method of motion estimation based on block matching and motion refinement is proposed for frame interpolation.The new motion estimation is a two-stage method consisting of coarse searching and fine searching.Coarse searching aims to reduce the amount of calculation and the algorithm complexity,while fine searching is utilized to refine motion vectors for improving the final performance.In the stage of coarse searching,a new algorithm of motion refinement,that Angular-Distance Median Filter(ADMF),is proposed to correct wrong motion vectors,which can solve the blurry-problems resulted from overlapped situations.Overlapped situations mean that different blocks move towards similar position after the initial motion estimation.Experimental results show that the proposed approach outperforms the other compared approaches in subjective and objective evaluation.
