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

EpiS significantly outperforms state-of-the-art generalizable surface reconstruction methods under sparse-view settings, while maintaining strong generalization without per-scene optimization.

C2weakest assumption

That coarse cost-volume features can reliably guide fine-grained epipolar feature aggregation and that a pretrained monocular depth model supplies unbiased scale-invariant global and local constraints that align with the multi-view epipolar geometry (abstract, paragraph on geometry regularization strategy).

C3one line summary

EpiS improves generalizable neural surface reconstruction from sparse views by guiding epipolar feature aggregation with cost volumes, using an epipolar transformer, and applying pretrained monocular depth constraints, outperforming prior methods on DTU and BlendedMVS.
