Phy-CoSF: Physics-Guided Continuous Spectral Fields Reconstruction and Super-Resolution for Snapshot Compressive Imaging

Bihan Wen, Ce Zhu, Gang Yan, Jiantao Zhou, Shigang Wang, Wudi Chen, Xin Yuan, Zhiyuan Zha, Zipei Fan

Phy-CoSF embeds continuous spectral fields as dynamic priors inside unfolding networks to reconstruct hyperspectral images at any wavelength from a single CASSI measurement.

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

Phy-CoSF not only achieves continuous modeling at arbitrary spectral resolutions but also outperforms many state-of-the-art methods in both reconstruction fidelity and spectral detail preservation.

C2weakest assumption

The assumption that embedding implicit neural representations as dynamic priors inside unfolding stages will faithfully preserve the underlying physics of CASSI while enabling continuous spectral synthesis without introducing artifacts or requiring post-hoc tuning.

C3one line summary

Phy-CoSF enables continuous spectral reconstruction and super-resolution for snapshot compressive imaging by integrating physics-guided deep unfolding with implicit neural representations in a two-phase architecture.
