Photometric Mesh Optimization for Video-Aligned 3D Object Reconstruction [PDF]
Computer Vision and Pattern Recognition, 2019 In this paper, we address the problem of 3D object mesh reconstruction from RGB videos. Our approach combines the best of multi-view geometric and data-driven methods for 3D reconstruction by optimizing object meshes for multi-view photometric ...

On the Data Reduction of WET Observations
Open Astronomy, 2003 It is demonstrated how the length of a continuous time-series of photometric data and their gaps affect the power spectrum of a Fourier Transform of the data.

Calibrated griz magnitudes of Tycho stars: All-sky photometric calibration using bright stars [PDF]
, 2008 Photometric calibration to 5% accuracy is frequently needed at arbitrary celestial locations; however, existing all-sky astronomical catalogs do not reach this accuracy and time consuming photometric calibration procedures are required.

Photometric redshift calibration with self-organising maps [PDF]
Astronomy & Astrophysics, 2019 Accurate photometric redshift calibration is central to the robustness of all cosmology constraints from cosmic shear surveys. Analyses of the Kilo-Degree Survey (KiDS) re-weighted training samples from all overlapping spectroscopic surveys to provide a ...

Atmospheric Extinction Corrections for WET Observations
Open Astronomy, 2003 Account of the extinction in the Earth’s atmosphere is an important part of the WET light curve reduction procedures. Usually, WET observations are not corrected for the second order extinction effects: the dependence of the extinction coefficient on ...

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 ...

Seismology Of A Massive Pulsating Hydrogen Atmosphere White Dwarf [PDF]
, 2012 We report our observations of the new pulsating hydrogen atmosphere white dwarf SDSS J132350.28+010304.22. We discovered periodic photometric variations in frequency and amplitude that are commensurate with nonradial g-mode pulsations in ZZ Ceti stars ...

On a New Technique for Discovering Variable Stars
Open Astronomy, 2003 A technique for discovering variable stars based on the calculation of the correlation coefficients is proposed. Applications of the technique are shown on the results of numerical experiments and on the Hipparcos photometric data.

Advanced Engineering Materials, EarlyView.Lithium‐mediated electrocatalysis enables sustainable N2 fixation but hindered by parasitic Li deposition. An oxide‐oxide nanocomposite (LiVO3/LiZnVO4) structurally integrates lithium into active sites, suppressing plating and enhancing N2 activation and HER supression.
