摘要

本文提出了一种基于等矩形投影(ERP)的编码树单元(CTU)分割提前终止算法，用于360度视频的高效视频编码(HEVC)帧内预测。该算法基于ERP投影的畸变特性，自适应地在HEVC CTU分割中采用早期终止，在视频帧的上下部分生成均匀区域。实验结果表明，该方法平均节省24%的时间，编码效率损失0.11%，显著降低了编码复杂度，对编码效率影响较小。此外，与所有相关工作相比，该方案考虑了节省时间和编码效率的关系，具有最佳效果。

ERP-Based CTU Splitting Early Termination for Intra Prediction of 360 videos

This work presents an Equirectangular projection (ERP) based Coding Tree Unit (CTU) splitting early termination algorithm for the High Efficiency Video Coding (HEVC) intra prediction of 360-degree videos. The proposed algorithm adaptively employs early termination in the HEVC CTU splitting based on distortion properties of the ERP projection, that generate homogeneous regions at the top and bottom portion of a video frame. Experimental results show an average of 24% time saving with 0.11% coding efficiency loss, significantly reducing the encoding complexity with minor impacts in the encoding efficiency. Besides, solution presents the best results considering the relation between time saving and coding efficiency when compared with all related works.
