Recent progress on photometric stereo extends the technique to deal with general materials
and unknown illumination conditions. However, due to the lack of suitable benchmark data …

In this paper, we present a technique for estimating the geometry and reflectance of objects
using only a camera, flashlight, and optionally a tripod. We propose a simple data capture …

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 …

We propose a novel formulation for joint recovery of camera pose, object geometry and
spatially-varying BRDF. The input to our approach is a sequence of RGB-D images captured …

Three-dimensional reconstruction of objects from shading information is a challenging task
in computer vision. As most of the approaches facing the Photometric Stereo problem use …

Photometric stereo (PS) techniques nowadays remain constrained to an ideal laboratory
setup where modeling and calibration of lighting is amenable. To eliminate such restrictions …

Abstract 3D shape recovery using photometric stereo (PS) gained increasing attention in the
computer vision community in the last three decades due to its ability to recover the thinnest …

Recovering the 3D shape of an object from shading is a challenging problem due to the
complexity of modeling light propagation and surface reflections. Photometric Stereo (PS) is …

Shape from shading with multiple light sources is an active research area, and a diverse
range of approaches have been proposed in recent decades. However, devising a robust …

In this paper, we present a photometric stereo algorithm for estimating surface height. We
follow recent work that uses photometric ratios to obtain a linear formulation relating surface …
