Contrast optimization
Explanation
This image filter analyses the current grayscale distribution of an image and
optimizes them using a non-linear statistical method.
Recommended use
Use of this function is particularly recommended for images whose contrast
distribution does not make full use of the available grayscale value range.
Scope
This filter works only with X-ray exposures.
Activating the filter
➢ Click the button.
or
➢ Select
"[O]ptimize contrast"
from the pop-up menu
"[F]ilter"
.
or
➢ In the menu bar
"[A]nalysis"
/
"[F]ilter"
, select the menu item
"[O]ptimize
contrast"
.
Example
In this way, for instance, details within a very low-contrast, “faint” image can
be made visible.
CAUTION
The contrast optimization filter may furnish different grayscales in the
filtered image for identical brightness values in the original image, because
the relevant local environment is evaluated for optimization.
