Perceptual Quality Driven Point Cloud Compression for 6DoF 3D Point Cloud Streaming

A 6 Degree of Freedom (6DoF) 3D point cloud streaming system based on MPEG-Dynamic Adaptive Streaming over HTTP (DASH) is expected to improve immersiveness of communication. 3D point cloud requires a more extensive data size than the 2D and 360-degree video, and significant storage space for the DASH system is required. This paper proposes a perceptual-quality-driven DASH representation generation method to reduce the total data volume of required DASH representations. The evaluation results conclude that the proposed DASH recipe reduces significant server storage space (approximately 75% reduction) while keeping the perceptual quality of 6DoF 3D point cloud streaming compared to the previous bitrate-driven DASH recipe.
