Outline of Final Research Achievements |
This project aims to provide a high quality point cloud video streaming. In particular, we would like to solve the high complexity issue of the video encoding/decoding to facilitate the point cloud video transmission. Then we would like to use AI technologies, such as deep neural networks, to predict future viewing angle to eventually avoid transmitting the unwatched part of the point cloud video. We also would like to use the AI technologies, such as deep reinforcement learning, to manage the network resources to maximize the quality of point cloud video received by users. To provide the computation capacity required for the encoding, transcoding and decoding, AI technologies will also be used to help maximize the usage of the nearby available communication and computation resources. Prototype will be built to verify the performance and help adjust the designed schemes accordingly.
