| 摘 要： | 现有视频编码采用基于块的混合编码架构,利用预测、变换、量化和熵编码技术实现对视频信号的高效压缩.在现有架构基础上进一步优化,提供针对视频图像信号局部特性的更加灵活的处理和编码.基于机器学习的视频编码技术有望部分或全面地改变现有的混合编码框架,给视频编码带来新的研究思路.未来视频除了现有的二维平面视频,还需要编码面向AR/VR应用的球面视频数据和体视频数据,这些新的视频源数据格式也给视频编码技术研究带来新的机会和挑战.

| Abstract: | The current video coding uses block based hybrid architecture,which uses predictive,transform,quantization and entropy coding techniques to efficiently compress video signals.Further optimizations on current architectures provide more flexible processing and coding for local characteristics of video image signals.Video coding based on machine learning was expected to change the existing hybrid coding framework partially or comprehensively,and bring new research ideas to video coding.In addition to existing 2D video signal,the future of video also needs to spherical video coding and volumetric video coding for AR/VR applications,the new video source data format of the video encoding technology has brought new opportunities and challenges. |
