However, those studies underestimated the sensitivity for brightness differences in these animals (Scholtyssek and Dehnhardt 2013; Scholtyssek et al. 2008) and therefore did not control sufficiently for the relative brightness of the stimuli that the animals were trained to discriminate.
Suppose that is the perceived global brightness of an image and is the perceived brightness of the current MB, then the brightness sensitivity of the MB, is defined by (13).
Scientists seeking to provide a mathematical explanation for the phenomenon, long noticed by travelers, built a model that mimics the body's timekeeping cells, using factors like light sensitivity, the brightness of the light, and how much people's internal clocks are "skewed" from real time an offset that can be as long as 1 hour.
This expansion of sensitivity captures greater detail, and subtle nuances of brightness and tonality that bring the photo closer to what the human eye actually sees.
These fluorophores were based on optimization of both environmental sensitivity and brightness, as these factors together determine sensitivity in living cells [ 30].
In particular, its multiangular imaging design has enabled the application of algorithms that minimize sensitivity of the aerosol retrievals to the brightness of the underlying surface.
The correction factor F, denoted by F = I-labeled protein/I-labeled SUV, represents the intrinsic brightness of and sensitivity of the microscope for His8-p-Nephrin-Alexa488 vs OG-DHPE.
The sensitivity of FCS to particle size and brightness has been applied to the detection of protein aggregates in the cerebrospinal fluid of patients with Creutzfeldt-Jakob disease [ 4] and Alzheimer's disease [ 5], and to measurement of the protein von Willebrand factor in plasma [ 6].
"We are trying to exactly match the eye sensitivity of people, therefore needing less energy to perceive the same level of brightness," Liedenbaum says.
