RoomLight: A 2.5D Illumination Prior for Indoor Environments
Andreea Ardelean, Bernhard Egger
Ill-posed inverse problems require priors to constrain the solution space toward plausible outcomes. In inverse rendering, learned priors modeling the distribution of natural illum…
VENI: Variational Encoder for Natural Illumination
Paul Walker, James A. D. Gardner, Andreea Ardelean +2
Inverse rendering is an ill-posed problem, but priors such as illumination priors can help simplify it. Existing work either disregards the spherical and rotation-equivariant natur…
RENI++ A Rotation-Equivariant, Scale-Invariant, Natural Illumination Prior
James A. D. Gardner, Bernhard Egger, William A. P. Smith
Inverse rendering is an ill-posed problem. Previous work has sought to resolve this by focussing on priors for object or scene shape or appearance. In this work, we instead focus o…
The Sky's the Limit: Re-lightable Outdoor Scenes via a Sky-pixel Constrained Illumination Prior and Outside-In Visibility
James A. D. Gardner, Evgenii Kashin, Bernhard Egger +1
Inverse rendering of outdoor scenes from unconstrained image collections is a challenging task, particularly illumination/albedo ambiguities and occlusion of the illumination envir…
