Thermodynamic and structural studies of complexes of manganese(II), cobalt(II), nickel(II) and copper(II) with aminofuropyridine carboxamide [PDF]
Journal of the Serbian Chemical Society, 2003 Complexes of Mn(II), Co(II), Ni(II) and Cu(II) with 2-aminofuro[3,2-b]pyridine-3-carboxamide have been prepared. The stability constants of the formed complexes were determined at 20, 30, 40 and 50ºC at a fixed ionic strength, I = 0.1 mol dm-3 (KCl). The

Leveraging Photometric Consistency Over Time for Sparsely Supervised Hand-Object Reconstruction [PDF]
Computer Vision and Pattern Recognition, 2020 Modeling hand-object manipulations is essential for understanding how humans interact with their environment. While of practical importance, estimating the pose of hands and objects during interactions is challenging due to the large mutual occlusions ...

The New Ephemeris and Light Curve Analysis of V870 Ara by the Ground-Based and TESS Data
Open Astronomy, 2021 New CCD photometric observations and their investigation of the W UMa-type binary, V870 Ara, are presented. Light curves of the system were taken through BVIfilters from the Congarinni Observatory in Australia.

Deep Photometric Stereo for Non-Lambertian Surfaces [PDF]
IEEE Transactions on Pattern Analysis and Machine Intelligence, 2020 This paper addresses the problem of photometric stereo, in both calibrated and uncalibrated scenarios, for non-Lambertian surfaces based on deep learning.

The Clustering of DESI-like Luminous Red Galaxies Using Photometric Redshifts [PDF]
Monthly notices of the Royal Astronomical Society, 2020 We present measurements of the redshift-dependent clustering of a DESI-like luminous red galaxy (LRG) sample selected from the Legacy Survey imaging dataset, and use the halo occupation distribution (HOD) framework to fit the clustering signal.

Photometric Segmentation: Simultaneous Photometric Stereo and Masking [PDF]
2019 International Conference on 3D Vision (3DV), 2019 This work is concerned with both the 3D-reconstruction of an object using photometric stereo, and its 2D-segmentation from the background. In contrast with previous works on photometric stereo which assume that a mask of the area of interest has been computed beforehand, we formulate 3D-reconstruction and 2D-segmentation as a joint problem.

Photometric Visual Servoing [PDF]
IEEE Transactions on Robotics, 2011 This paper proposes a new way to achieve robotic tasks by 2D visual servoing. Indeed, instead of using classical geometric features such as points, straight lines, pose or a homography, as is usually done, the luminance of all pixels in the image is here considered.

Gaia Data Release 1. Summary of the astrometric, photometric, and survey properties [PDF]
, 2016 At about 1000 days after the launch of Gaia we present the first Gaia data release, Gaia DR1, consisting of astrometry and photometry for over 1 billion sources brighter than magnitude 20.7.

Type Ia supernova Hubble diagrams with host galaxy photometric redshifts [PDF]
JCAP 10(2022) 065, 2022 The case of SN Ia Hubble diagrams from photometrically selected samples using photometric SN host galaxy redshifts is investigated. The host redshift uncertainties and the contamination by core collapse SNe are addressed. As a test, we use the 3-year photometric SN Ia sample of the SuperNova Legacy Survey (SNLS), made of 437 objects between 0.1 and 1 ...

Self-Calibrating Deep Photometric Stereo Networks [PDF]
Computer Vision and Pattern Recognition, 2019 This paper proposes an uncalibrated photometric stereo method for non-Lambertian scenes based on deep learning. Unlike previous approaches that heavily rely on assumptions of specific reflectances and light source distributions, our method is able to ...
