论文摘要
在本文中，我们提出了一种基于跨块差异的VVC内部编码的新快速CU分区算法。这种差异是通过从分区获得的梯度和含量来衡量的，并用于指导不必要的水平和垂直分区模式跳过。通过此指南，可以快速确定块分区。与VVC相比，我们提出的方法可以节省41.64％（平均）编码时间，而BD速率仅增加0.97％（平均）增加。
In this paper, we propose a new fast CU partition algorithm for VVC intra coding based on cross-block difference. This difference is measured by the gradient and the content of sub-blocks obtained from partition and is employed to guide the skipping of unnecessary horizontal and vertical partition modes. With this guidance, a fast determination of block partitions is accordingly achieved. Compared with VVC, our proposed method can save 41.64% (on average) encoding time with only 0.97% (on average) increase of BD-rate.
