High-efficiency video coding encoders provide great improvements in coding efficiency and can also support higher resolution and multiple coding tools. The new coding structures such as coding unit (CU) and prediction unit (PU) have helped a lot, but the computational complexity is much higher than those of previous standards. This paper proposes a fast algorithm combining with CU and PU early termination decisions to reduce computational demand. Based on the analytic results, we can set up an adaptive threshold that can be obtained for early termination. Meanwhile, we also develop an adaptive search range determination according to the motion vector (MV). Compared with HM 12.0, our proposed method achieves an approximate 57% time saving, whereas the average Bjøntegaard-Delta Bit-rate (BDBR) increase is only 0.43%. In addition, our fast algorithm outperforms the previous works in both coding speed and coding performance.

基于运动信息的高效CU和PU决策用于HEVC的帧间预测

高效的视频编码器可以极大地提高编码效率,还可以支持更高的分辨率和多种编码工具。诸如编码单元(CU)和预测单元(PU)之类的新编码结构起到了很大的作用,但是计算复杂度比以前的标准高得多。本文提出了一种结合CU和PU提前终止决策的快速算法,以减少计算需求。根据分析结果,我们可以设置一个自适应阈值,该阈值可用于提前终止。同时,我们还根据运动矢量(MV)开发了自适应搜索范围确定。与HM 12.0相比,我们提出的方法可节省约57%的时间,而平均Bjøntegaard-Delta比特率(BDBR)增长仅为0.43%。此外,
