OctHilNet: Hilbert-Guided Hierarchical Geometry Codec for Octree-Structured LiDAR Point Clouds

High-quality LiDAR point cloud (LPC) compression is essential for the storage and transmission of 3D data. The octree-structured entropy codec has emerged as the predominant method; however, previous methods do not fully utilize spatial contextual information, due to the loss of local features cause…
