Researchers have developed ELiC, a novel framework designed to enhance the efficiency of LiDAR geometry compression. This system utilizes cross-bit-depth feature propagation, allowing lower-depth features to inform predictions at higher depths. Additionally, a Bag-of-Encoders selection scheme dynamically chooses the optimal coding network based on occupancy statistics, adapting capacity without needing separate models for each level. The framework also incorporates a Morton-order-preserving hierarchy to maintain global Z-order, reducing latency by eliminating per-level sorting. AI
