Differential judgement values use the basic gradation of the differences
between the model and measurement object images. Differential judgement
values can be set between 1 and 255. Pixels in areas with a difference greater
than the differential judgement value are converted to 1 (white) and all other
pixels are converted to 0 (black). Thus, only the defects are converted to white
pixels and are measured.
The default differential judgement value of 50 is usually sufficient, but change
this value if the defects are not being detected properly.

value are converted to 1 (white).
All other pixels (no difference to
