摘　　要：提出一种H.264编码中帧间模式选择的算法,利用帧与帧之间的时间相关性并提出通过模式识别中统计分类的方法对帧间宏块模式进行分类。实验表明,本算法在编码性能下降可忽略的情况下,使编码时间有显著减少。In this paper, we have proposed an inter-mode selection algorithm for H.264, which is based on the time-relativity of the neighboring frames and adopts the idea of statistic classification. The simulation results show that with this algorithm we can achieve significant time reduction while maintaining the PSNR and bit rate.
