Furthermore, the survival of secondary aggregates was significantly higher in low brightness than in both other situations (Figure 5. Significant difference between low brightness and medium or high brightness, Log Rank test, Log rank statistic = 5.4, p = 0.02 and 3.9, p = 0.047 for Low vs. Medium and Low vs. High brightness comparisons, respectively).
An elaborate five-mirror optical assembly divides the incoming light between the sensors — but dilutes the brightness in the process, leaving both the optical viewfinder and, in low light, the L.C.D. screen dimmer than you'd like.
Indeed, in the first 15 minutes, global aggregation was faster in high brightness than in medium or low brightness (Figure 3a; Kruskal-Wallis test, KW values>6.66, p<0.05 followed by Dunn's test: C≠B and C≠A, p < 0.05).
Indeed, at 10 minutes, 60% of woodlice were already aggregated in high brightness compared to 35% in medium and low brightness (Figure 3b; χ2 test, df = 2, χ2 = 6.79, p = 0.034).
In Figure 9c, the shadows are over detected when compared with the ideal shadow images, while in Figure 9d, some low brightness shadow areas are not detected.
To date the most limiting factor for the use of fluorescent nanodiamonds in biology is the low brightness of the NV- center.
As a result of movement, motion blur, featureless tissue sites and low brightness in certain spectral ranges, accurate registration of the multispectral images becomes a challenging and time-consuming task.
With the aim to solve the out-of-focus and low brightness problems in OLVF images, a restoration framework called online video ferrography out-of-focus restoration (OLVFOFR) is developed.
(Uranus and Neptune were also Greek and Roman gods, but neither planet was known in Antiquity because of their low brightness. Their names were assigned by later astronomers).
Then we remove low brightness pixels in the GIST area by setting those pixels' brightness as 255 if the brightness is no higher than 40. Figure 2(d) shows the result of the proposed procedures.
In the resulting images, pixels with a high difference of brightness are rendered bright, while pixels with no or with low brightness difference are displayed in black or dark grey colors.
