Primary Use Center If True, the measurement starting point is half way between the Primary
and Secondary Endpoint Positions
Primary Blob Color
To F i nd
Bright, Dark, or both color objects on the Primary Wide Line ROI
Primary Blob
Threshold Method
See “Grey Level Threshold Types” on page 3-68 for more details.
Primary Fixed Blob
Threshold Percent-
age
The grey level threshold value for fixed single threshold types (in per-
centage)
Primary Adaptive
Blob Threshold Off-
set
If Adaptive Threshold Method is selected, this offset is added to the
adaptive threshold. This allows you to weight the adaptive threshold up
or down.
Primary Noise
Level
The amount of background noise present in the image along the Primary
Wide Line ROI. Higher noise means the edges must be farther apart.
Lower noise allows edges that are closer together.
Primary Maximum
Number Of Edges
To F i nd
Limits the number of edges found along the Primary Wide Line ROI to
those with the strongest transition
Primary Edge Pat-
tern
The edge pattern to find along the Primary Wide Line ROI (Rising indi-
cates a transition from dark to light; Falling indicates a transition from
light to dark)
Primary Subpixel
Method
Indicates how many subpixel points to average when finding the edge
points along the Primary Wide Line ROI. More points used provides
greater accuracy but takes more time. See “Subpixel Method” on
page 3-125.
Primary Subpixel
Position
The subpixel position for edges that are not well defined. See “Subpixel
Position” on page 3-144.
Primary Subpixel
Search Distance in
Pixels
The maximum distance, in pixels, that the subpixel algorithm will search
from the threshold edge for the subpixel edge. See “Subpixel Search
Distance” on page 3-125.
Secondary End-
point Position
The ending point for the measurement, beginning from the tail end of the
Secondary Wide Line ROI
Secondary Use
Center
If True, the measurement starting point is half way between the Primary
and Secondary Endpoint Positions
Secondary Blob
Color To Find
Bright or Dark objects on the Secondary Wide Line ROI
Secondary Blob
Threshold Method
See “Grey Level Threshold Types” on page 3-68 for more details.
Secondary Fixed
Blob Threshold Per-
centage
The grey level threshold value for fixed single threshold types (in per-
centage)
