1 giorno fa · Chromatic pupillometry has been performant in retrospective studies aiming to detect glaucoma, with a sensitivity and specificity up to 95.6% and 94.2% respectively at advanced stages [53, 55 ...
5 giorni fa · Chromatic information is reported to enhance memory for visual scenes , and conversely, the color appearance of objects with diagnostic hues is influenced by memory . Nevertheless, and despite the prominence of color in perceptual experience and neurophysiology, recognition performance is remarkably resilient to color changes ( 13 – 18 ).
4 giorni fa · The detection of chromatic effects of microlensing, neither supports the presence of BHs. Detailed statistical studies of the observed microlensing magnifications and events frequency impose strict upper limits to the fraction of total mass of BHs ($\ltsim$ 1\%) from $10^{-7}M_\odot$ to indefinitely large masses.
6 ore fa · Just like a human engineer would do in inspection process, the machine vision inspection process consists of two steps: Imaging (the “seeing”) and analyzing (the “thinking”); the latter requires a stable software and computing power, together with an algorithm that has defining parameters for errors, like the diameters of irregularities, or chromatic data for discolors.
6 ore fa · “Traditional imaging systems consist of a cascade of refractive elements that correct for aberrations, and these bulky lenses impose a lower limit on camera footprint. A further fundamental barrier is a difficulty of reducing focal length, as this induces greater chromatic aberrations.” But these researchers appear to have overcome these ...
4 giorni fa · Firstly, LLW is used for qualitative detection of CFRP-strengthened steel structures by calculating the waveform energy as a detection index. Secondly, a sweep frequency-nonlinear response (SFNR) method based on the swept excitation, LLW, and nonlinear analysis is proposed to determine the optimal excitation frequency of LVT.
