Photometric Stereo With Area Light for Object-Level Surface Reconstruction
IEEE AccessA traditional photometric stereo method estimates surface normals with point lights placed at infinity, suffering from geometric errors when the light has a planar shape and is near the object. Though the light sampling approach improves the accuracy, it

The hidden science of haptics: A pedagogical review of tactile evaluation in cosmetics
International Journal of Cosmetic Science, Volume 48, Issue 3, Page 600-634, June 2026.This review explores the physiological basis of tactile perception and critically examines classical and emerging sensory methods used in cosmetics, advocating for broader methodological integration and recognition of sensory analysis in the field. Abstract Sensory analysis is a cornerstone of cosmetic development, yet remains underrepresented in peer ...

A combined multi-view stereo and photometric stereo approach
, 2022 Two approaches to 3D-reconstruction from images, Multi-view Stereo and Photometric Stereo, are combined as a means of completing missing areas within the partly-complete reconstruction returned by the first approach.

Multiview Photometric Stereo Using Planar Mesh Parameterization
, 2013 We propose a method for accurate 3D shape reconstruction using uncalibrated multiview photometric stereo. A coarse mesh reconstructed using multiview stereo is first parameterized using a planar mesh parameterization technique.

Multispectral Photometric Stereo for Acquiring High-Fidelity Surface Normals
, 2014 Multispectral imaging and photometric stereo are common in 3D imaging but rarely have been combined. Reconstructing a 3D object's shape using photometric stereo is challenging owing to indirect illumination, specular reflection, and self-shadows ...

Average surface roughness evaluation using 3-source photometric stereo technique
International Journal of Metrology and Quality Engineering, 2016 This paper presents a technique for measuring surface roughness (Ra), using photometric stereo method. The method utilizes three or more images of the measured surface from the same viewpoint, taken sequentially under different illumination conditions ...

On Generating Synthetic Datasets for Photometric Stereo Applications
ComputersThe mathematical model for photometric stereo makes several restricting assumptions, which are often not fulfilled in real-life applications. Specifically, an object surface does not always satisfies Lambert’s cosine law, leading to reflection issues ...
