Abstract

In this paper, the effect of motion vector accuracy on the efficiency of motion compensated frame rate up conversion (MC-FRUC) is studied. The motion vector processing problem is formulated and analyzed via motion vector modelling. A processing scheme is proposed to improve the interpolated frame quality at the decoder. The practical application of integrating the motion vector processing algorithm in a standard H.263 decoder for MC-FRUC is also discussed. Experimental results show that a 0.4-0.6 dB gain in the H.263 codec, and a 0.5-2 dB gain in off-line frame rate conversion can be obtained by the proposed algorithm.
