| Popis: |
In H.264, the optimal coding mode for each macroblock (MB) is selected by exhaustively searching all MB modes in the multiple reference frames. The exhaustive mode search has a very high computational complexity. This paper proposes three different approaches along with their combination to reduce the complexity of the rate-distortion optimized mode decision process in H.264. These approaches are based on transform-domain properties and spatio-temporal correlation in video sequences. Experimental results demonstrate that the proposed methods achieve around 5-7 times improvement in average speedup with good prediction quality and comparable bitrate. |
