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.
