Linear Morphology Open
In the Image Filtering Drawer
The Linear Morphology Open tool removes small noise in an image, like the Morphology Open tool, but this
tool keeps thin lines in the image during the process. (See “Morphology” on page 3-52 for more details.)
Target Intensity
Selection
Brightest Row/Column Average Is Target Intensity: After projecting the
rows/columns of the sensor ROI, the tool finds the brightest row/column
and scales all the other row/columns to have that same average inten-
sity. It is automatic self-scaling behavior that preserves greyscale resolu-
tion. If the overall input image intensity goes up and down, then the
output image intensity also goes up and down, even after it is leveled.
Fixed Target Intensity: The rows/columns are scaled so that their aver-
age intensity is the Fixed Target Intensity value. This setting helps adjust
the image to a fixed average intensity and can help with fixed threshold-
ing in other tools. It takes some adjustment of the Fixed Target Intensity
value to keep the image bright and not saturated.
Fixed Target Inten-
sity
The tool levels the pixel intensities to this greyscale value when Target
Intensity Selection is set to Fixed Target Intensity.
Output Name What it is
Output Image The leveled Region To Copy. Displayed on the Output Image tab.
Input Name What it is
Input Image Linked Image
Tool Origin The tool’s origin relative to the entire image space.
Shape List The desired region of the image to process. If no shape is defined, the
entire image is processed.
Number of Itera-
tions
The number of times to perform the operation. If zero is entered, the tool
just copies the input image to the output.
Keep 0 Degree
Lines
If True, lines in the image that are not rotated remain after processing.
Keep 45 Degree
Lines
If True, lines in the image that are rotated 45 degrees remain after pro-
cessing.
Keep 90 Degree
Lines
If True, lines in the image that are rotated 90 degrees remain after pro-
cessing.
Keep 135 Degree
Lines
If True, lines in the image that are rotated 135 degrees remain after pro-
cessing.
