During training, the proposed cross-branch HDR consistency loss provides explicit supervision for HDR content
Implicationpartial
Directly stated as a core contribution and solution to a stated problem in the abstract and introduction.

Evidencepartial
an illumination-guided gradient scaling strategy mitigates exposure-biased gradient starvation and reduces under-densified representations.
Implicationpartial
Directly stated as a core contribution and method in the abstract and summary.
Verificationpartial

Evidencepartial
Without modeling illumination in 3D space, environment-dependent attributes of the scene are largely underexplored.
Implicationpartial
Directly stated as a limitation of prior work in the analysis/related work section.
Verificationpartial

Evidencepartial
a physically inspired HDR-NVS framework that models scene appearance via intrinsic reflectance and adjustable ambient illumination.
Implicationpartial
Directly stated as the core physical inspiration and modeling approach in the abstract and framework overview.
Verificationpartial
partial
Evidencepartial
PhysHDR-GS employs a complementary image-exposure (IE) branch and Gaussian-illumination (GI) branch to faithfully reproduce standard camera observations and capture illumination-dependent appearance changes, respectively.
Implicationpartial
Directly stated as the core architectural design in the abstract and contribution summary.
Verificationpartial
partial
Evidencepartial
Implicitly supervising HDR content by constraining tone-mapped results fails in correcting abnormal HDR values, and results in limited gradients for Gaussians in under/over-exposed regions.
Implicationpartial
Directly stated as a problem with prior approaches in the abstract, which the proposed method aims to solve.
