一种基于宏块平稳性的帧内宏块模式选择算法
n Intra-Frame Macroblock Mode Selection Algorithm based on Macroblock’s Stationarity
H.264/AVC是新一代的视频压缩标准,编码的压缩率很高,但带来的副作用却是编解码器复杂度的增加,从而很难达到实时的要求。本文提出了一个基于宏块平稳性的帧内模式选择算法。该算法在帧内预测前,先对宏块的平稳性进行判断,然后选择一种宏块模式进行预测,减少了算法的复杂度。通过实验证明,在比特率和信噪比变化很小的情况下,I帧的编码耗时有很大幅度的下降。
H.264/AVC is the new generation of video coding protocol with a higher efficiency,but the by-effect is increasing the complexity of the protocol H.264 codec.Thereby it is difficult to achieve the real-time application. An Intra-Frame Macroblock Mode Selection Algorithm based on Macroblock’s Stationarity is proposed in this paper.This algorithm will predict every macroblock\
