In many situations the reflectance function of a surface is approximately linear, and there is
an effielent closed-form solution to the shape-from-shading problem. When boundary …

Well-known methods for solving the shape-from-shading problem require knowledge of the
reflectance map. Here we show how the shape-from-shading problem can be solved when …

The method described here for recovering the shape of a surface from a shaded image can
deal with complex, wrinkled surfaces. Integrability can be enforced easily because both …

It is known that most real surfaces are neither perfectly diffuse (Lambertian) nor ideally
specular (mirror-like); however, most shape-from-shading algorithms assume Lambertian …

The authors propose to combine a triangular element surface model with a linearized
reflectance map to formulate the shape-from-shading problem. The main idea is to …

Existing shape-from-shading algorithms assume constant reflectance across the shaded
surface. Multi-colored surfaces are excluded because both shading and reflectance affect …

We present a new method for the recovery of a bivariate function H (x, y) that describes a
“nice,” almost everywhere differentiable height profile, from shading information. The given …

Surface reconstruction from stereo and shape-from-shading have both been discussed
extensively in the literature. In this paper methods that attempt to supplement stereo with …

We develop a systematic approach to the discovery of parallel iterative schemes for solving
the shape-from-shading problem on a grid. A standard procedure for finding such schemes …

Many algorithms have been suggested for the shape-from-shading problem, and some
years have passed since the publication of the survey paper by Zhang et al.[R. Zhang, P.-S …
