Fast macroblock inter mode decision and motion estimation for H.264/MPEG-4 AVC
In H.264/MPEG-4 AVC, MacroBlock (MB) mode decision and motion estimation (ME) is one of the most computationally expensive processes. This paper proposes a fast intermode decision and ME algorithm. Experimental results show that the proposed algorithm could achieve similar Rate-Distortion (R-D) performance with about 50% computation saving, compared to the JM low-complexity mode with a Fast Full-Search (FFS) motion estimation algorithm.
