A Fast Mode Selection Algorithm Using Texture Analysis for H.264/AVC
H.264/AVC, the newest international video coding standard
achieves higher compression efficiency as compared to all
other existing coding standard such as MPEG-4 and H.263.
However this efficiency comes with a dramatic increase in
computational complexity due to several advanced
techniques, such as inter mode and intra mode prediction
with variable size motion compensation. It adopts rate
distortion optimization (RDO), while maximizing visual
quality and minimizing the required bit rate. In this paper,
we propose a fast inter mode selection algorithm. The aim
is to reduce the number of modes in intra and inter mode
prediction. Experimental results show that this algorithm
reduces the total encoding time with little loss of bit rate
and visual quality.
