| Summary:
This paper shows that motion vectors representing the true motion of an
object in a scene can be exploited to improve the encoding process of computer
generated video sequences. Therefore, a set of sequences is presented for which
the true motion vectors of the corresponding objects were generated on a
per-pixel basis during the rendering process. In addition to conventional
motion estimation methods, it is proposed to exploit the computer generated
motion vectors to enhance the ratedistortion performance. To this end, a motion
vector mapping method including disocclusion handling is presented. It is shown
that mean rate savings of 3.78% can be achieved.
