Histogram is an image enhancement technique which normalizes gray level
in the image.
Significant differences were also observed in various morphological traits of the ligulate flowers (petals) -mean blue, red, green and gray level
-and the stems-mean blue, red, and green, gray level
, and brown:green area ratio.
processing may be overkill for a certain application, and binary thresholding with its higher speed could be more attractive.
A quantitative analysis of stress whitening (scratch visibility) in terms of the change in gray level
([DELTA]G-difference in gray level
of scratch deformed and unscratched specimen) with respect to unscratched specimen is presented in Fig.
The gray level
image of 'foot pressure distribution' is divided into matrix form and the average value of each matrix element is determined in pseudo gray colour, which provides information about the degree of abnormality of the foot.
Everything darker than a certain gray level
, selected according to the contrast between the objects and their background, is represented by a one; everything lighter than that is a zero.
eMagin also is using pulse width modulation (PWM) pixel hold times for the first time to virtually eliminate motion artifacts in video imagery, with the extra benefit of providing better dimming range and gray level
response for low light and night vision applications.
In the figure, a gray level
indicates the height at the corresponding location in the field as a brighter pixel represents higher elevation.
This would prevent some material from sneaking through off-line statistically based tests on a gray level
Within this region of interest, an average gray level
value is measured representing solder presence.
This results in a measure of the degree of the mutual dependence of the gray levels
of two images, or, put differently, of the degree to which a given gray level
of one image can predict gray levels
in the other.
The values of a gray level
image belongs to J [subset] M.
