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

Extensive experiments demonstrate that our method achieves state-of-the-art performance on SV AG-ReID scenarios.

C2weakest assumption

Large-scale 3D mesh reconstruction from single real viewpoints can produce geometrically consistent novel views across diverse categories without predefined templates, and synthetic-to-real bias can be sufficiently mitigated for effective generalization.

C3one line summary

3D-LENS formalizes single-view aerial-ground re-identification and uses 3D lifting for novel view synthesis plus bias-mitigating representation learning to achieve SOTA cross-view matching.
