为了减少H.264/AVC帧间编码模式选择的计算复杂度,利用编码模式之间的相关性以及视频序列时空域的相关性,提出了有选择性的小块搜索技术和有选择性的帧内编码模式搜索技术。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 computational complexity of H.264 / AVC inter-frame coding mode selection and to exploit the correlation between coding modes and the correlation of time-space domain in video sequences, a selective small block search technique and selective frame Internal coding mode search technology. The simulation results show that the proposed algorithm can greatly reduce the computational complexity of mode selection under the premise of maintaining the distortion performance, which is in favor of the real-time application of H.264.
