✓ Portable graph bundle live · download bundle · merged state

The bundle contains the canonical record plus signed events. A mirror can host it anywhere and recompute the same current state with the deterministic merge algorithm.

Claims

C1strongest claim

VOIC outperforms existing monocular SSC methods in both geometric completion and semantic segmentation accuracy, achieving state-of-the-art performance on the SemanticKITTI and SSCBench-KITTI360 benchmarks.

C2weakest assumption

The assumption that offline extraction of visible-region voxel labels from dense 3D ground truth cleanly separates supervision without introducing selection bias or losing critical information needed for coherent global reasoning.

C3one line summary

VOIC decouples monocular 3D scene completion into visible semantic perception and occluded reasoning via VRLE and a dual-decoder architecture, achieving state-of-the-art results on SemanticKITTI and SSCBench-KITTI360.
