Paper Abstract

We have developed a Motion Vector (MV) Synthesis algorithm for an MPEG2-to-MPEG4 transcoder. MPEG2 bitstream parameters are utilized to adaptively scale and refine the MPEG2 MVs to synthesize MPEG4 MVs. The simulation results show that our MV Synthesis algorithm produces results that are equivalent to VM Full Search in both coding efficiency and subjective image quality, with significant reduction in complexity.
