Luminosity and Contrast Adjustment of Fundus Images with Reflectance
Applied Sciences, 2023 This paper presents an automatic correction method for luminosity and contrast variation in fundus images. Sixty retina or fundus images with different levels of reflectance are selected from online databases and used to assess the effectiveness of the ...

Luminosity and photometry [PDF]
Proceedings of the Royal Society of London, 1897 The luminosity of the spectrum was determined by what may be term ed the method of the “minimal effective stimulus.” Through the partition separating two dark rooms from each other a hole was drilled 1 mm. across; this was covered with a piece of ground glass.

A Mini-survey of X-ray Point Sources in Starburst and Non-Starburst Galaxies [PDF]
, 2002 We present a comparison of X-ray point source luminosity functions of 3 starburst galaxies (the Antennae, M82, and NGC 253) and 4 non-starburst spiral galaxies (NGC 3184, NGC 1291, M83, and IC 5332).

Luminosity function of GRBs [PDF]
Astronomy & Astrophysics, 2001 We attempt to constrain the luminosity function of Gamma Ray Bursts (GRBs) from the observed number count--flux relation and the afterglow redshift data. We assume three classes of luminosity functions for our analysis: (a) Log-normal distribution, (b) Schechter distribution, and (c) Scale-free distribution. We assume several models of the evolution of

Angle-Aware and Tone-Aware Luminosity Analysis for Paper Model Surface
Tehnički Vjesnik, 2021 Luminosity contributes to the paper model surface perception. It has a significant impact on the perception of colour and details. The main purpose of this paper is to study the reflection luminosity of paper model surface which can be of complex or ...

The overdensities of galaxy environments as a function of luminosity and color [PDF]
, 2002 We study the mean environments of galaxies in the Sloan Digital Sky Survey as a function of rest-frame luminosity and color. Overdensities in galaxy number are estimated in $8 h^{-1} \mathrm{Mpc}$ and $1 h^{-1} \mathrm{Mpc}$ spheres centered on $125,000$
