Outline of Annual Research Achievements

Point cloud video is the most popular representation of hologram, which is the medium to precedent natural content in VR/AR/MR, and is expected to be the next generation video by providing users with better immersive viewing experience. Point cloud video has wide applications in Society 5.0 such as for online education and entertainment. To further enhance these applications, networked point cloud video is in critical demand.

This project aims to solve the core technical questions for a high quality point cloud video streaming and promote the applications of point cloud video in Society 5.0. Towards this goal, we have mainly considered: 1) survey the state-of-the-art schemes of point cloud video streaming system, 2) how to design transmission friendly or scalable point cloud video codec, and 3) how to utilize AI to build MEC for the point cloud video streaming, in the first year.

Part of the results have been published in IEEE journals and conferences

Current Status of Research Progress
Current Status of Research Progress

2: Research has progressed on the whole more than it was originally planned.

Reason

According to the schedule, we focus on the survey, the codec design, MEC design in the first year. Although some of the exchanges have been delayed due to covid, the overall progress is smooth

Strategy for Future Research Activity

Based on the obtained results, next year we will focus on the following three technical challenges:
1. AI-empowered point cloud video transmission
2. AI-inspired MEC for point cloud video transmission
3. solving the issues of the high-complexity codec for point cloud video transmission
