spond to the first defect, defect points 4, 5, 6, and 7 (the next four) correspond to the second defect, and the
final five points are the third defect.
Input Name What it is
Input Image Linked Image
Tool Origin The tool’s origin relative to the entire image space
Polygon List A list of objects to inspect for defect bulges
Window Width Cumulative turn angles are accumulated over this total length of the
curve. Defect points are marked at the middle vertex of the curve.
Flatness Length The minimum boundary length that declares the end of a defect. If the
flatness length is exceeded between defect points, the defect is consid-
ered terminated between them.
Cumulative Turn
Angle in Degrees
The minimum angle turn needed to signal a defect point. This is called
'cumulative' because it is accumulated over several vertices.
Defect points are reported only if there is more than one with opposite
turn directions with no flatness termination between them. This criterion
makes the tool able to distinguish between corners and defect bumps.
Bump Type Find Both: The tool finds both concave and convex bumps
Find Convex: The tool finds only bumps that protrude outward from the
boundary.
Find Concave: The tool finds only bumps that are indented into the
boundary.

ter
If True, only defects that exceed the Minimum Point Count value is
included in the Defect List
