Abstract: Size conversion is a pivotal step of MPEG-4 shape coding. This paper proposes a modifying size conversion algorithm for MPEG-4 shape coding base on the research of MPEG-4 video verification model. The simulation result shows that the algorithm is fast in coding speed and small in calculate quantity.
