Kavli Affiliate: Jing Wang | First 5 Authors: Pengpeng Yu, Pengpeng Yu, , , | Summary: LiDAR point clouds are fundamental to various applications, yet high-precision scans incur substantial storage and transmission overhead. Existing methods typically convert unordered points into hierarchical octree or voxel structures for dense-to-sparse predictive coding. However, the extreme sparsity of geometric […]
