Motion-based competitive spatio-temporal technique with multi-frames references for efficient H.264/AVC motion information prediction

Motion estimation and compensation is an essential part of several video coding standards. Moreover motion information takes significant part of compressed bit stream, especially in low bit rate situation. This paper proposes an efficient technique which merges motion-based competitive spatio-temporal technique and multi-frames references scheme for efficient motion information prediction. Simulation results show an improved coding efficiency, compared to conventional H.264/AVC codec, with minimum computational complexity over a wide range of test sequences, especially for higher spatial resolutions.
