The paper applies the motion vector (MV) correction and refinement algorithm to frame up-rate conversion (FRUC) in order to enhance the quality of the interpolated frame. The motion compensated frame interpolation (MCFI) methods using bilateral motion estimation and hierarchical block matching algorithm are used to form the interpolated frame. Simulation results show that MV correction algorithm provides true motion vectors and MV refinement helps reducing the blocking artifact.
