Abstract
With the development of immersive media technologies such as virtual reality and augmented reality, the presentationm, storage and transmission of immersive video has received a lot of attention in both research and industry field. Due to the more complex video characteristics and huge data volume, the traditional coding techniques are not efficient for immersive video coding. How to present and encode the immersive video more efficiently is a challenge. Based on the Degree of Freedom (DoF), 3DoF and 6DoF formats of immersive video are introduced respectively in this paper. Firstly, 3DoF video related coding techniques including projection model, motion estimation are introduced, and then, 3DoF video coding standard is discussed. In 6DoF format video coding, the video representation, virtual viewpoint synthesis techniques, 6DoF video coding techniques and Moving Picture Experts Group Immersive Video (MPEG, MIV) video coding standard are illustrated. Finally, the development of immersive video and its coding technology is summarized and prospected. © 2024 Science Press. All rights reserved.
