Video-based Point Cloud Compression Artifact Removal
Anique Akhtar, Wen Gao, Li Li +3
Photo-realistic point cloud capture and transmission are the fundamental enablers for immersive visual communication. The coding process of dynamic point clouds, especially video-b…
Occupancy-map-based rate distortion optimization for video-based point cloud compression
Li Li, Zhu Li, Shan Liu +1
The state-of-the-art video-based point cloud compression scheme projects the 3D point cloud to 2D patch by patch and organizes the patches into frames to compress them using the ef…
Hybrid Point Cloud Attribute Compression Using Slice-based Layered Structure and Block-based Intra Prediction
Yiting Shao, Qi Zhang, Ge Li +1
Point cloud compression is a key enabler for the emerging applications of immersive visual communication, autonomous driving and smart cities, etc. In this paper, we propose a hybr…
Attribute Compression of 3D Point Clouds Using Laplacian Sparsity Optimized Graph Transform
Yiting Shao, Zhaobin Zhang, Zhu Li +2
3D sensing and content capture have made significant progress in recent years and the MPEG standardization organization is launching a new project on immersive media with point clo…
Co-projection-plane based 3-D padding for polyhedron projection for 360-degree video
Li Li, Zhu Li, Xiang Ma +2
The polyhedron projection for 360-degree video is becoming more and more popular since it can lead to much less geometry distortion compared with the equirectangular projection. Ho…
An Efficient Four-Parameter Affine Motion Model for Video Coding
Li Li, Houqiang Li, Dong Liu +4
In this paper, we study a simplified affine motion model based coding framework to overcome the limitation of translational motion model and maintain low computational complexity.…
Projection based advanced motion model for cubic mapping for 360-degree video
Li Li, Zhu Li, Madhukar Budagavi +1
This paper proposes a novel advanced motion model to handle the irregular motion for the cubic map projection of 360-degree video. Since the irregular motion is mainly caused by th…
Pseudo Sequence based 2-D hierarchical reference structure for Light-Field Image Compression
Li Li, Zhu Li, Bin Li +2
In this paper, we present a novel pseudo sequence based 2-D hierarchical reference structure for light-field image compression. In the proposed scheme, we first decompose the light…
