Boundary Inspections
Boundary inspections match the boundary areas (areas where the density
changes).
• OFF
This method masks the boundary, excluding it from inspection. This
means that any defects near the boundary will not be detected. The
boundary level sets the number of pixels near the boundary that will be
excluded from the inspection.
See page 1-(53).
Model
1 square = 1 pixel
• ON*
The whole area is inspected and defects near the boundary will be
detected. The processing time, however, will be longer because eroded
and dilated models are matched to prevent inspection mistakes caused by
measurement object displacement. Only defects detected for both models
will be judged as defects. The size of dilation and erosion can be set using
the boundary level.
The asterisk (*) indicates the default setting.

If the measurement object is
displaced slightly higher, the
boundary will be detected as
differing from the registered
model.
When Boundary inspection is
OFF: The range of pixels set
for the boundary level are
excluded from the
measurement on both sides of
the boundary.
