WebThe ground reflectance, for solar radiation (integrated wavelengths), can range from about 0.05 to 0.90 accord- ing to the nature of the terrain. The three fluxes of incoming solar radiation are connected by the relationship I sin h = T - D, where J is the direct radiation at normal incidence, T and D0 respectively the total and diffuse ... WebSurface reflectance and illumination level, which are confounded in the retinal image, must be disentangled by the visual system and a theory of lightness must explain how. Thus, a theory of surface lightness should also be a theory of perceived illumination and describe the relationship between them.
WebIn this paper, we present a method that estimates reflectance and illumination information from a single image depicting a single-material specular object from a given class under natural illumination. We follow a data-driven, learning-based approach trained on a very large dataset, but in contrast … WebWe employ a novel computational illumination setup consisting of a rotating arc of controllable LEDs which sweep out programmable spheres of incident illumination during 1-second exposures. We illuminate the object with a succession of spherical harmonic illumination conditions, as well as photographed environmental lighting for validation.
