Detecting Multiple Illuminants
The presence of multiple illuminants in an image is an obstacle for many computer vision algorithms as well as most illuminant estimation algorithms. Multiply lit scenes do, however, occur in many situations, such as the presence of shadows or daytime indoor environments. Common ways to minimize the problems created by multiple lights are to perform a given task only in regions containing a sin...
متن کاملassessment of the efficiency of s.p.g.c refineries using network dea
data envelopment analysis (dea) is a powerful tool for measuring relative efficiency of organizational units referred to as decision making units (dmus). in most cases dmus have network structures with internal linking activities. traditional dea models, however, consider dmus as black boxes with no regard to their linking activities and therefore do not provide decision makers with the reasons...
A luminous efficiency function , V * ( 1 ) , for daylight adaptation
We propose a new luminosity function, V ð1Þ, that improves upon the original CIE 1924 Vð1Þ function and its modification by D. B. Judd (1951) and J. J. Vos (1978), while being consistent with a linear combination of the A. Stockman & L. T. Sharpe (2000) long-wavelength-sensitive (L) and middle-wavelength-sensitive (M) cone fundamentals. It is based on experimentally determined 25 Hz, 2diameter,...
متن کاملAlternatives to Outdoor Daylight Illumination for Photodynamic Therapy—Use of Greenhouses and Artificial Light Sources
Daylight-mediated photodynamic therapy (daylight PDT) is a simple and pain free treatment of actinic keratoses. Weather conditions may not always allow daylight PDT outdoors. We compared the spectrum of five different lamp candidates for indoor "daylight PDT" and investigated their ability to photobleach protoporphyrin IX (PpIX). Furthermore, we measured the amount of PpIX activating daylight a...
متن کاملSimulating Artificial Stock Markets with Efficiency
Stock markets have been studied for years in economy and finance academic departments by relying on the idea of a general homo economicus that makes rational choices. Classical approaches use equational representation to enable a global markets characterization, but they fail to explain the link between individual behaviours and the global market dynamic and trends that emerge. Schelling semina...
