摘要
为了减少H.264/AVC帧间编码模式选择的计算复杂度,利用不同编码模式在实际视频序列中的利用率信息及空时域相邻块之间的相关性,提出了一个低复杂度的快速帧间编码模式选择算法。模拟结果表明,该算法在保持率失真性能的前提下可以大幅度减少模式选择的计算复杂度,有利于H.264的实时应用。
In order to reduce the encoding complexity of macroblock coding mode decision in H.264/AVC, a fast inter mode selecting algorithm is proposed for H.264 by making use of high correlation of rate-distortion costs between spatial adjacent and temporal adjacent blocks and the adoption information of these inter modes in actual sequences. Simulation results demonstrate that the proposed method provides significant improvement in computational requirement, with negligible small picture quality degradation and slight bit rate increase,
