Sentence examples for mean brightness over from inspiring English sources

The ciliary beat frequency for each time point was determined by analyzing the change in mean brightness over time in a small area of an individual ciliated cell by fast Fourier transformation using Autosignal 1.7 (SeaSolve Software Inc., San Jose, CA, USA).

Though the successional trajectories are highly nonlinear in the early years of succession, a linear model fits well the regional mean successional trajectories for brightness and greenness due to significant cross-site variations that masked the nonlinearity over a regional scale (R2 = 0.8951 for regional mean brightness with age; R2 = 0.9348 for regional mean greenness with age).

Calculate the mean brightness within the region.

Mean brightness is an indicator of the illumination level.

These include the mean brightness, entropy, contrast, and gradient.

In order to mitigate over-enhancement problems, brightness preserving bi-histogram equalization (BBHE) [19], dualistic sub-image histogram equalization (DSIHE) [20], and minimum mean brightness error bi-histogram equalization (MMBEBHE) [21] have been proposed, which partition a histogram before applying the HE.

Afterwards, minimum mean brightness error bi-histogram equalization (MMBEBHE) was suggested [26] to reach a greater level of brightness preservation without revealing the unwanted artifacts by using a minimum absolute mean brightness error (AMBE) function.

The mean brightness of each ROI is determined using numerical values assigned to grey-scale pixels.

Fig. 6 Statistics (box plots) of test results: a mean brightness, b entropy, c gradient, d contrast.

where E(X) and E Y) are the mean brightness of the images X and Y, respectively.

MMBEBHE recursively partitions the image histogram into multiple groups based on mean brightness error (MBE).
