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 …

Shape recovery of an object based on shading variations resulting from different light
sources has recently been reconsidered. Improvements have been made that allow for the …

This article formulates a near-lighting shape-from-shading problem with a pinhole camera
(perspective projection) and presents a solution to reconstruct the Lambertian surface of …

This article proposes a solution of the Lambertian shape from shading (SFS) problem in the
case of a pinhole camera model (performing a perspective projection). Our approach is …

We deal with an inverse problem where we want to determine the surface of an object using
the information contained in two or more pictures which correspond to different light …

This paper describes a new modeling of the shape from shading problem taking perspective
projection into account, and proposes a method of resolution for the new equation. An …

This paper presents a model-based vision system for dentistry that will assist in diagnosis,
treatment planning, and surgical simulation. Dentistry requires an accurate three …

Document digitization is faster and more affordable using digital cameras than scanners. On
the other hand, if we aim at extending the basic digital camera functionalities for such a …

The online detection of the three-dimensional (3D) shape of a weld pool is a key unsolved
question for weld shape control. In this paper, a method to reconstruct the 3D shape of a …

We describe a mathematical and algorithmic study of the Lambertian “Shape-From-Shading”
problem for orthographic and pinhole cameras. Our approach is based upon the notion of …
