[Mask Zone] – Use 1 as an example. Next to the edge points the adjacent 1 pixel
point is masked as untest.
[Inspection Parameter] – Set the parameters for inspection. The system only
inspects the area that is in the ROI box and not masked.
[Inspect Sensitivity] – Use 60 as an example. If the difference of gray level
between neighboring pixels is larger than 40 (100-60) the two pixels will be
regarded as edges.
[Tolerance] – Use 5 as an example. If a group size of edges is more than 5 the
inspection window will be regarded as failed.
The [Train Sensitivity] value must be bigger than [Inspect Sensitivity] or it will result
in more false alarms.
