Motion Vector Processing Based on Residual Energy Information for Motion Compensated Frame Interpolation
In this paper, we address the problem of motion compensated frame interpolation (MCFI) at the decoder by analyzing received motion vectors (MVs) and residual error. In the proposed method, the skipped frames are generated at the decoder by using received information from the bitstream. We combine a hierarchical motion vector correction algorithm and a residual-energy constrained median filter to obtain true motion. Experimental results show that the proposed motion vector processing algorithm improves the visual quality of interpolated frames, especially in the motion transition area and the motion boundary.
