Shape from defocus can not therefore be based on them. On the other hand, since shading is due to surface orientation, and thus

WebbSfS yields the shape of objects, but not absolute distances like triangulation systems do. The shape information is derived from the shading of continuous smooth surfaces. The … WebbShape-from-shading is an interesting approach to the prob- lem of nding the shape of a face because it only requires one image and no subject participation. However, SfS is not accurate enough to pro- duce good shape models. Previously, SfS has been combined with shape models to produce realistic face reconstructions.
