Shape-from-shading: a survey
TL;DR: Six well-known SFS algorithms are implemented and compared, and the performance of the algorithms was analyzed on synthetic images using mean and standard deviation of depth error, mean of surface gradient error, and CPU timing.
Journal ArticleDOI
Shape from intensity gradient
Ruo Zhang,Mubarak Shah +1 more
TL;DR: A new shape-from-shading (SFS) algorithm which replaces the brightness constraint with an intensity gradient constraint is proposed, which obtains the solution by the minimization of an error function over the entire image.
Journal ArticleDOI
Iterative shape recovery from multiple images
Ruo Zhang,Mubarak Shah +1 more
TL;DR: This paper presents a method which recovers shape from a sequence of images taken with different illumination directions, which can be of any length, and given in any order, as long as the light source directions are not coplanar.
