Multiview Photometric Stereo [PDF]
IEEE Transactions on Pattern Analysis and Machine Intelligence, 2008 This paper addresses the problem of obtaining complete, detailed reconstructions of textureless shiny objects. We present an algorithm which uses silhouettes of the object, as well as images obtained under changing illumination conditions. In contrast with previous photometric stereo techniques, ours is not limited to a single viewpoint but produces ...

Summary study of data-driven photometric stereo methods
Virtual Reality & Intelligent Hardware, 2020 Background: A photometric stereo method aims to recover the surface normal of a 3D object observed under varying light directions. It is an ill-defined problem because the general reflectance properties of the surface are unknown.

Example-Based Multispectral Photometric Stereo for Multi-Colored Surfaces
Journal of Imaging, 2022 A photometric stereo needs three images taken under three different light directions lit one by one, while a color photometric stereo needs only one image taken under three different lights lit at the same time with different light directions and ...

Identifying the lights position in photometric stereo under unknown lighting [PDF]
, 2021 Reconstructing the 3D shape of an object from a set of images is a classical problem in Computer Vision. Photometric stereo is one of the possible approaches.

Photometric stereo for strong specular highlights
Computational Visual Media, 2018 Photometric stereo is a fundamental technique in computer vision known to produce 3D shape with high accuracy. It uses several input images of a static scene taken from one and the same camera position but under varying illumination. The vast majority of

Polarisation photometric stereo [PDF]
Computer Vision and Image Understanding, 2017 This paper concerns a novel approach to fuse two-source photometric stereo (PS) data with polarisation information for complete surface normal recovery for smooth or slightly rough surfaces. PS is a well-established method but is limited in application by its need for three or more well-spaced and known illumination sources and Lambertian reflectance ...

Color Photometric Stereo Using Multi-Band Camera Constrained by Median Filter and Occluding Boundary
Journal of Imaging, 2019 One of the main problems faced by the photometric stereo method is that several measurements are required, as this method needs illumination from light sources from different directions.
