Fast decision algorithm of H.264 intra-prediction mode
Yunyan Zhou · Journal of Shandong Institute of Light Industry · 2011
In the H.264 video codec standard,the intra prediction predicts the current block with surrounding pixels to reduce the spatial redundancy.It can greatly improve the coding efficiency of H.264.But the acquisition of intra prediction mode of access requires a very complex operation;its usefulness can be reduced.By utilizing the time domain,spatial correlation to predict the best mode of the current block,unnecessary calculation mode selection can be reduced by combining with early termination algorithm.Experimental results show that the proposed algorithm can guarantee that without changing the output rate the encoding time can be greatly reduced and coding efficiency can be improved.
