运动估计是许多视频编码标准(如 MPEG-2、H.264/AVC 和 HEVC)中的重要过程。尽管运动估计已在编码器中使用,但预计它将在未来消费设备的分布式视频编码架构中使用。但运动估计本身会消耗超过 50% 的编码复杂度或编码时间。为了减少计算时间,提出并实现了许多快速运动估计算法。本文提出了一种新的快速 ME 算法,其性能优于 HEVC 参考软件 HM 中实现的快速 ME 算法。
Motion Estimation is an essential process in many video coding standards like MPEG-2, H.264/AVC and HEVC. Despite Motion Estimation has been used at the encoder, it is expected to be used in future consumer devices in the distributed video coding architectures. But the Motion Estimation itself consumes more than 50% coding complexity or time to encode. To reduce the computation time, many fast Motion Estimation Algorithms were proposed and implemented. The present paper proposes a new fast ME algorithm which outperforms the fast ME algorithm implemented in HEVC reference software HM.
