Correction of UBV Photometry for Emission Lines
Open Astronomy, 2003 We investigate the effect on U,B,V magnitudes of the removal of emission lines from the spectra of some symbiotic stars and novae during their nebular phases.

Photometric Redshifts of Quasars [PDF]
, 2001 We demonstrate that the design of the Sloan Digital Sky Survey (SDSS) filter system and the quality of the SDSS imaging data are sufficient for determining accurate and precise photometric redshifts (``photo-z''s) of quasars.

Photometric redshifts for the CFHTLS T0004 Deep and Wide fields [PDF]
, 2008 We compute photometric redshifts based on the template-fitting method in the fourth public release of the Canada-France-Hawaii Telescope Legacy Survey. This unique multi-colour catalogue comprises u*,g',r',i',z' photometry in four deep fields of 1 deg2 ...

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.

SuperNova Acceleration Probe (SNAP): Investigating Photometric Redshift Optimization [PDF]
, 2007 The aim of this paper is to investigate ways to optimize the accuracy of photometric redshifts for a SNAP like mission. We focus on how the accuracy of the photometric redshifts depends on the magnitude limit and signal-to-noise ratio, wave-length ...

Photometric Ambient Occlusion [PDF]
2013 IEEE Conference on Computer Vision and Pattern Recognition, 2013 We present a method for computing ambient occlusion (AO) for a stack of images of a scene from a fixed viewpoint. Ambient occlusion, a concept common in computer graphics, characterizes the local visibility at a point: it approximates how much light can reach that point from different directions without getting blocked by other geometry.

Comparative Study of Light Sources for Household
Management Systems in Production Engineering, 2017 The article describes test results that provided the ground to define and evaluate basic photometric, colorimetric and electric parameters of selected, widely available light sources, which are equivalent to a traditional incandescent 60-Watt light bulb.
