Stereo-photometric techniques for scanning micrometer scale [PDF]

Virtual Archaeology Review, 2015
This paper describes a new methodology based on the combination of photogrammetric and stereo-photometric techniques that allows creating virtual replicas reproducing the relief in micrometric scale, with a geometric resolution until 7 microns. The finest details of the texture obtained by photogrammetric methods are translated to the relief of the ...

Combining geometric and photometric 3D reconstruction techniques for cultural heritage [PDF]

Journal of Cultural Heritage
There are mainly two families of photographic 3D reconstruction techniques.Photogrammetry techniques work according to the principle of triangulation, from the matching of dierent views, while photometric techniques link the appearance of a 3D point to the orientation of its normal, relative to that of the incident light. While photogrammetry allows to

A comprehensive introduction to photometric 3D-reconstruction [PDF]

, 2020
Photometric 3D-reconstruction techniques aim at inferring the geometry of a scene from one or several images, by inverting a physical model describing the image formation.

Velocimetry of red blood cells in microvessels by the dual-slit method: Effect of velocity gradients [PDF]

, 2012
The dual-slit is a photometric technique used for the measurement of red blood cell (RBC) velocity in microvessels. Two photometric windows (slits) are positioned along the vessel.

Tiled Projector Displays Correction for Dark Scenes in Railway Simulators [PDF]

, 2011
Tiled projector displays are a common choice for training simulators, where a high resolution output image is required. They are cheap for the resolution that they can reach and can be configured in many different ways.

Glancing through the debris disk: Photometric analysis of DE Boo with CHEOPS [PDF]

, 2023
DE Boo is a unique system, with an edge-on view through the debris disk around the star. The disk, which is analogous to the Kuiper belt in the Solar System, was reported to extend from 74 to 84 AU from the central star. The high photometric precision of

Surface Shape Studies of the Art of Paul Gauguin [PDF]

, 2015
Starting in the 1890s the artist Paul Gauguin (1848- 1903) created a series of prints and transfer drawings using techniques that are not entirely understood. To better understand the artist's production methods, photometric stereo was used to assess the

Microstructure Reconstruction in Battery Electrodes Using Machine Learning Based on Low‐Voltage Focused Ion Beam–Scanning Electron Microscopy Tomography Images

Advanced Engineering Materials, EarlyView.
Low‐voltage FIB‐SEM tomography combined with a image preprocessing pipeline improves phase contrast and enables reliable machine‐learning segmentation of conductive networks in lithium‐ion battery electrodes. Structural descriptors are extracted from segmented images, done semimanually and automated, and compared.

Photometric techniques using small college research instruments for study of the extrasolar planetary transits of HD 209458 [PDF]

, 2002
We present the results of a program to develop techniques that enable high-resolution photometric measurements using modest research instruments available to small colleges, and then demonstrate those techniques in a pilot photometric project. Using a 25
