Shape from Shading Under Coplanar Light Sources
In this paper image-based techniques for 3D surface reconstruction are presented which are especially suitable for (but not limited to) coplanar light sources. The first approach is based on a single-image shape from shading scheme, combined with the evaluation of at least two further images of the scene that display shadow areas. The second approach allows the reconstruction of surfaces by an ...
متن کاملShape from Shading Using Near Point Light Sources
1 The Approximate Solution Curve Tracing (ASCT) Method 1.1 The correct solution space (CSS) Figure 1: The CSS represents the correct solution .space which all of the depth values on the illuminated object are included in. LB is the lower bound of the CSS. All of the depth values on the illuminated object will be not "deeper" than it. UB is the upper boumt of the CSS. All of the depth values on ...
متن کاملLight Source Dependence in Shape from Shading
We investigated shape constancy in human shape from shading under variations of illuminant direction using a local attitude probe in conjunction with a perturbation analysis. Stimuli were computer generated and depicted ellipsoids in a structured setting. Even with these simple shapes subjects settings were systematically biased in the illuminant direction and were consistent with a regression ...
متن کاملLight fields and shape from shading.
From a theoretical point of view, the use of the shading cue involves estimates of the light field and thus observers need to judge the light field and the shape simultaneously. The conventional stimulus in perceptual experiments, a circular disk filled with a monotonic gradient on a uniform surround, represents a local shading or tonal gradient. In typical scenes, such gradients vary smoothly ...
متن کاملAn Improved Shape from Shading
We propose an improved shape from shading (SFS) algorithm which is an extension of the recently published algorithm by Zheng and Chellappa 13]. A markedly more accurate estimate of the azimuth of the illumination source is presented. Depth reconstruction has been improved upon by using a new set of boundary conditions and adapting a more sophisticated technique for hierarchical implementation o...
