Photometric Linearization under Near Point Light Sources
نویسندگان
چکیده
We present a method for generating linearized images that consist of only diffuse reflection from images taken under near point light sources. Previous photometric linearization method cannot work under near point light sources, since it assumes parallel light. For satisfying this assumption, our method utilizes a photometric linearization method by dividing images into small regions. It also selects linearization coefficients from regions. Experimental results show that the proposed method can generate accurate linearized images even if images are obtained under near point light sources, and show that the method can correctly classifies the photometric factors.

Uncalibrated Near-Light Photometric Stereo
Photometric stereo (PS) [3] is a technique to accurately recover the normal map of a 3D scene from several pictures (at least three) taken from the same view point and under different illumination conditions. When the light directions and intensities are known, photometric stereo can be solved as a linear system. When the illumination is not known, one needs to solve a much harder problem: unca...
متن کاملNear Field Photometric Stereo with Point Light Sources
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 photometric stereo approach to serve as a competitive alternative to other shape reconstruction methods. However, most photometric stereo methods tend to ignore factors that are relevant in practical applications. The setup...
متن کاملPhotometric Stereo: Lambertian Reeectance and Light Sources with Unknown Direction and Strength
This paper reconsiders the familiar case of photometric stereo under the assumption of Lambertian surface re ectance and three distant point sources of illumination. Here, it is assumed that the directions to and the relative strengths of the three light sources are not known a priori. Rather, estimation of these parameters becomes part of the problem formulation. Each light source is represent...
متن کاملSemi-calibrated Near-Light Photometric Stereo
We tackle the nonlinear problem of photometric stereo under close-range pointwise sources, when the intensities of the sources are unknown (so-called semi-calibrated setup). A variational approach aiming at robust joint recovery of depth, albedo and intensities is proposed. The resulting nonconvex model is numerically resolved by a provably convergent alternating minimization scheme, where the ...
متن کاملAccuracy of Spherical Harmonic Approximations for Images of Lambertian Objects under Far and Near Lighting
Various problems in Computer Vision become difficult due to a strong influence of lighting on the images of an object. Recent work showed analytically that the set of all images of a convex, Lambertian object can be accurately approximated by the low-dimensional linear subspace constructed using spherical harmonic functions. In this paper we present two major contributions: first, we extend pre...
