摘要

本文提出了一种基于跨块差分的VVC编码快速分块方法。这种差异是通过从分区中获得的梯度和子块的含量来测量的，并用于指导跳过不必要的水平和垂直分区模式。有了这个指导，就可以快速确定块分区。与VVC相比，该方法平均节省41.64%的编码时间，而bd率仅提高0.97%。

Cross-Block Difference Guided Fast CU Partition for VVC Intra Coding

In this paper, we propose a new fast CU partition method for VVC intra coding based on the 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.
