Abstract

Versatile Video Coding (VVC) is going to be the successor of High Efficiency Video Coding (HEVC). The new standard (currently under development) requires the adoption of tools that provide a good trade-off between gain and implementation complexity. In previous work we proposed a Line-Based Intra Prediction (LIP) algorithm to improve the coding performance of the upcoming standard. However, that contribution did not sufficiently take into account the hardware-related complexity of the method. For this reason, this publication addresses these problems and proposes several modifications of the algorithm to solve them. Experimental results show an average gain of 1.0% and 0.5% for the All Intra (AI) and Random Access (RA) configurations, respectively.

基于行内预测的视频编码硬件友好扩展

多功能视频编码(VVC)是高效视频编码(HEVC)的后继技术。新标准(目前正在开发中)要求采用在增益和实现复杂性之间提供良好权衡的工具。在之前的工作中，我们提出了一种基于线的内预测(LIP)算法来提高即将发布的标准的编码性能。然而，这一贡献并没有充分考虑到该方法与硬件相关的复杂性。因此，本出版物解决了这些问题，并提出了对算法的几种修改来解决这些问题。实验结果表明，All Intra (AI)和Random Access (RA)配置的平均增益分别为1.0%和0.5%。
