It is shown that the temperature difference between the bright and dark colored top wing surface is around 10 °C.
Our basic idea is described as below: Firstly, we compute the difference between the bright channel and the dark channel: I^{text{difference}}_{text{channel}}(x)=I^{text{bright}}(x -I^{text{dark}}(x -I^{text{dark
The lack of detection of the Y feature in the LIR data suggests little brightness temperature difference between the bright arms and the stem of the feature and the neighboring region seen at short wavelengths, which is a puzzle.
A single parameter, TD2, is the threshold for gray-scale difference between the bright spots and their neighborhood.
The differences between the bright (bottom) and dark (top) sides are readily apparent in the wide area view shown in Figure 3a, even though differences in relative intensity are muted when the sample is viewed at this angle.
These variations are recorded by a detector system; the image contrast Contim is defined as the ratio of the difference between brightest ρmax and darkest ρmin points in the image and the average intensity ρ̅ of the whole image: The image contrast resulting from absorption of part of the incident beam is known as amplitude contrast.
When pimonidazole was injected 90 min or more before intratumour injection of Hoechst, there was no significant difference between the hypoxic fraction of the Hoechst brightest or dimmest cells, that is, the hypoxic fraction was similar for cells lining the track of the needle or distant from the track.
Although the lines appear broadened in the fluorescence micrographs because of the resolution limit inherent in a conventional optical characterization tool, it is significant that the very bright contrast difference between the GFP-functionalized nanolines and the surrounding surface is being observed for features that are only 70 nm wide.
Thus, this stripe was easier to detect than if the involved stripe was dark because the difference in signal intensity between the bright stripe and the tumor were more obvious than that between the dark stripe and the tumor.
In Figure 11, each compared method produces unnatural image appearance, which is caused by over-enhancing the dark regions while preserving the regional brightness difference between dark and bright areas in the image.
