Astroinformatics of galaxies and quasars: a new general method for photometric redshifts estimation [PDF]
Monthly Notices of the Royal Astronomical Society, 2011 With the availability of the huge amounts of data produced by current and future large multi-band photometric surveys, photometric redshifts have become a crucial tool for extragalactic astronomy and cosmology.

The GALANTE Photometric System [PDF]
Monthly Notices of the Royal Astronomical Society, 2019 This paper describes the characterization of the GALANTE photometric system, a seven intermediate- and narrow-band filter system with a wavelength coverage from 3000 $\r{A}$ to 9000 $\r{A}$ .

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 ...

An Attempt to Construct an Activity Cycle Catalog with Kepler Long-Cadence Light Curves
Universe, 2022 Many stars show activity cycles like the Sun. Kepler has gathered ∼200,000 light curves. Most of the Kepler stars only have long-cadence light curves, which limits their applicable methods.

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.

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

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 ...

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.
