Webb1 jan. 1989 · It may be concluded that shading effects arise primarily because some parts of a surface are oriented so as to reflect more of the incident light toward the viewer than are others. It should be... WebbIdeal shading images, as used for shape from shading (SFS), are assumed to have been captured under the general reflectance-map conditions, including orthographic projec-tion, and so they carry no depth-related blur. Shape from defocus can not therefore be based on them. On the other hand, since shading is due to surface orientation, and thus
