WebNov 13, 2024 · We propose a self-supervised lighting estimation through light space discretization and perform image relighting (using the estimated lightings) along with image reconstruction. We model the specularities explicitly using estimated illumination and albedo refinement. WebPhotometric lights use photometric (light energy) values that enable you to more accurately define lights as they would be in the real world. You can create lights with various distribution and color characteristics, or import specific photometric files available from lighting manufacturers.
