Abstract

Motion vectors are side information vital to motion-compensated predictive/interpolative interframe video coding algorithms. This paper is concerned with the coding efficiency for this motion information. It is demonstrated that coding differential motion vectors is not always advantageous. An adaptive strategy is thus considered to automatically select the most favorable mode to code the motion information. The effects of video noise to motion estimation and coding are also investigated. A simple linear filtering scheme is used to reduce the noise effects. Simulation results show a significant performance improvement for noisy video by using this simple filtering scheme.
