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 such as online education and entertainment. This project aims to solve the core technical questions for a high quality point cloud video streaming.
Towards this goal, we have mainly considered 1) how to better predict the user viewing angle, and 2) how to utilize AI to schedule the point cloud video streaming, including distributed control method, 3) implementation of the system.
Part of the results have been published in IEEE journals and conferences.
