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

our approach significantly outperforms state-of-the-art baselines, generating high-fidelity egocentric videos with realistic interactions and exhibiting exceptional cross-embodiment generalization to robotic hands.

C2weakest assumption

Sparse 3D hand joints plus the occlusion-aware weighting mechanism are assumed to supply enough geometric and semantic information to prevent motion inconsistencies and hallucinations under severe egocentric occlusions without additional human-centric priors.

C3one line summary

A new occlusion-aware control module generates high-fidelity egocentric videos from sparse 3D hand joints, supported by a million-clip dataset and cross-embodiment benchmark.
