Shape from Shading in the Light of Mutual Illumination
Shape from shading schemes are based on the assumption that image radiance is a function of surface normal alone. Unfortunately, because surfaces illuminate one another, radiance is a complicated global property of surface shape. We review briefly the equations governing mutual illumination effects, and demonstrate that mutual illumination forms a major component of image radiance. We then disc...
متن کاملShape and Illumination from Shading using the Generic Viewpoint Assumption
The Generic Viewpoint Assumption (GVA) states that the position of the viewer or the light in a scene is not special. Thus, any estimated parameters from an observation should be stable under small perturbations such as object, viewpoint or light positions. The GVA has been analyzed and quantified in previous works, but has not been put to practical use in actual vision tasks. In this paper, we...
متن کاملA Variational Approach to Shape-from-Shading Under Natural Illumination
A numerical solution to shape-from-shading under natural illumination is presented. It builds upon a generic PDE-based formulation which handles directional or spherical harmonics lighting, orthographic or perspective projection, and greylevel or multi-channel images. An augmented Lagrangian solver is proposed, which separates the global, nonlinear optimization problem into a sequence of simple...
متن کاملShape , Illumination , and Reflectance from Shading Supplementary Material
Choosing good error metrics for this task is challenging. We will use the geometric mean of six error metrics: two for shape, one for illumination, one for shading, one for reflectance, and the MIT intrinsic images error metric introduced in [4], which we will refer to as RS-MSE (though which the original authors call “LMSE”). We use the geometric mean of these metrics as it is insensitive to t...
متن کاملIllumination-Insensitive Face Recognition Using Symmetric Shape-from-Shading
Sensitivity to variations in illumination is a fundamental and challenging problem in face recognition. In this paper, we describe a new method based on symmetric shape-from-shading (SSFS) to develop a face recognition system that is robust to changes in illumination. The basic idea of this approach is to use the SSFS algorithm as a tool to obtain a prototype image which is illumination-normali...
