摘要
H.264提供了4×4的亮度块帧内预测,其共有9种预测模式。在判断其预测模式中要求4×4块的每种预测模式都要判断,因此计算复杂度很高。有效减少4×4块预测模式的判断次数,在实时视频编码过程中很有价值。基于此,提出了一种帧内4×4块预测模式判断提前退出的优化算法,并对其进行了试验,得到了很好的效果。
Intra prediction of 4×4 luma hlock has 9 prediction modes in H.264. Each prediction mode needs to be checked to each 4×4 block, so it has great complexity. In the process of real-time video coding, it is valuable to reduce the checking times to 4×4 blocks. Because of this, in this paper an advanced Algorithm to end the calculation sooner is proposed, and good performance is achieved in experiments.
