Detecting Binary Defects
Section 2-12
location of the measurement object can be determined using the edge detec-
tion points so the measurement region can be adapted to suit if the size or
position of the measurement object changes.
Once the edges have been located, the image is converted to binary and the
area and center of gravity of the measurement region is measured.

STEP 1: Changing Binary Level for Each Region
Perform this operation to change the binary level for each region.
Set the level for converting 256-gradation images into binary images. Mea-
surements are performed for the white pixels. Therefore, make the settings so
that the measurement object is white.
CHECK
If Binary defect/Binary (Common) are changed after the binary levels are
changed for each region, the settings for each region are disabled and the set-
ting levels under Binary defect/Binary (Common) are enabled.
