Shape from Shading

Categories: Vision


Author(s): T.P. Pridmore, S.R. Pollard, S.T. Stenton

The process of extracting three-dimensional shape information from smooth gradations of reflected light intensity. It has been shown by Horn that if certain assumptions are made concerning the reflectance function and illumination of a surface it is possible to formulate and solve equations relating surface shape to the measured intensities in an image of the surface. See Intrinsic Images.
