Extreme Difference
In the Flaw Detection Drawer
The Extreme Difference tool detects defects indicated by a bright or dark region relative to the background.
Similar to the Spot Find Tool, this tool searches the ROI for bright or dark spots. However, since this tool is
used for detection instead of location, it uses a relative intensity difference rather than an absolute intensity
Minimum Point
Count
This is the minimum number of points a defect must contain to be
included in the Defect List
Use Area Filter If True, only defects with areas that lie within the Area Range is included
in the Defect List
Area Range A defect’s area must lie within this range to be included in the Defect
List. This is the area included between the first and last defect point in a
defect. Area values within a defect are negative for concave sections
and positive for convex sections. The parameters are start and end. The
parameters are start and end.
Use Deviation Filter If True, only defects with a deviation value that lies within the Deviation
Range is included in the Defect List.
Deviation Range The deviation is the maximum distance from a line connecting the first
and last defect point in the defect to the defect section’s highest or low-
est point. Deviation values are negative for concave sections and posi-
tive for convex sections. The parameters are start and end.
