Tīmeklis2024. gada 31. okt. · Light fields representing Lambertian scenes are characterized by specific epipolar plane images, which support in Fourier domain is limited by the … The situation for a Lambertian surface (emitting or scattering) is illustrated in Figures 1 and 2. For conceptual clarity we will think in terms of photons rather than energy or luminous energy. The wedges in the circle each represent an equal angle dΩ, of an arbitrarily chosen size, and for a Lambertian surface, the number of photons per second emitted into each wedge is proportional to the area of the wedge.
