Under this method, the difference image is used directly.
If the registered model and coated object can be captured at the exact
same position, there is no offsetting of images and therefore noises will

not generate due to difference extraction.
In this case, more accurate measurement is possible when the difference
image is used directly.
Under this method, pixels corresponding to specified values are deleted
from the outline of the extracted difference image.
This option is set to remove noises resulting from offset images when the
inspection object or camera has moved slightly.
Since information of several pixels are deleted from the difference image,
the measured coating width becomes smaller than the actual width.
Unchecked
0 to 9 Set the degree of assimilation of variations around boundaries.
