deviation between the dark and light parts of an image. Sliding the
contrast indicator to the left along the bar decreases the image’s
contrast. This results in a smaller standard deviation between dark and
light parts of an image. The midpoint position represents no applied
contrast, which is the default.
• Gamma, which is a way of logarithmically compensating for low intensity
pixels that may be present in some images. Only low intensity pixels
are affected. Sliding the bar to the right increases the gamma index for
the image; sliding it to the left decreases it. The midpoint of the scale
represents no gamma applied.
Threshold, which acts upon the current contrast setting, can be used to
adjust the level of contrast stretching. When the slider control is positioned
at the left side of the bar, no thresholding is applied. Maximum thresholding
of the contrast is applied when the slider control is at the far right side of the
bar.
