After thirty years of researching, the photometric stereo technique for 3D shape recovery still
does not provide reliable results if it is not constrained into very well-controlled scenarios. In …

Abstract 3D reconstruction from shading information through Photometric Stereo is
considered a very challenging problem in Computer Vision. Although this technique can …

Shape recovery based on shading variations of a lighted object was recently revisited with
improvements that allow for the photometric stereo approach to serve as a competitive …

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 …

Methods for 3D reconstruction such as Photometric stereo recover the shape and
reflectance properties using multiple images of an object taken with variable lighting …

We propose an uncalibrated photometric stereo method that works with general and
unknown isotropic reflectances. Our method uses a pixel intensity profile, which is a …

We present a method to capture both 3D shape and spatially varying reflectance with a multi-
view photometric stereo technique that works for general isotropic materials. Our data …

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 …

In this paper we present a variational approach to simultaneously recover the 3D
reconstruction, reflectance, lighting and specularities of an object, all of them, from a set of …

We present a recursive algorithm for 3D surface reconstruction based on photometric stereo
in the presence of highlights, and self and cast shadows. We assume that the surface …
