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 $\r{A}$ .

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.

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.

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.

SDSS Standard Star Catalog for Stripe 82: the Dawn of Industrial 1% Optical Photometry [PDF]
, 2007 We describe a standard star catalog constructed using multiple SDSS photometric observations (at least four per band, with a median of ten) in the $ugriz$ system.

Photometric Determination of Phospholipase A [PDF]
Clinical Chemistry and Laboratory Medicine, 1986 A photometric method for the determination of phospholipase A is described, in which fatty acids are liberated from phosphatidylcholine and measured by a discontinuous enzymatic test. Optimal test conditions were evaluated using purified phospholipase A from human and porcine pancreas.

Photoelectric Vilnius Photometry of Stars in the Mega Proper Motion Field KA 10
Open Astronomy, 2003 Photoelectric seven-color photometry in the Vilnius medium-band, system is obtained for 87 stars down to V≃13.0 in the Kiev proper motion field KA10 [l = 137°, b = -59°]. The size of the field is 1.4 square degrees.
