Low bit rate video coding based on three-dimensional discrete pseudo cosine transform

This paper proposes low bit rate video coding algorithm based on multiplication-free three-dimensional discrete pseudo cosine transform (3-D DPCT) and Context-Adaptive Binary Range Coder (CABRC). Video source rate control based on adaptive Lagrange multiplier selection is introduced. Practical results which show the compression efficiency of the proposed algorithm in comparison with H.264/AVC standard are presented.
