Abstract
The rapid advancement of 3D sensing and rendering technologies has expanded the use of point clouds across various fields. To address the challenge of managing large point clouds, Point Cloud Compression (PCC) has gained significant research interest in recent years. The Moving Picture Experts Group (MPEG) has played an important role in standardizing PCC by designing frameworks such as Solid Geometry-based Point Cloud Compression (Solid G-PCC), using octree and Trisoup to compress the geometry of dynamic point clouds. This paper introduces a skip coding mode to improve the inter-frame coding by early terminating octree and Trisoup node generation based on a rate-distortion optimization consideration. Experiments show a 6.3% average improvement in geometry coding efficiency.
