If “noise” persists in the binarized image, however, and superfluous “+” edge
markers appear on the gage, see the Binary Filter section for information
about “filtering” this noise.
Binary Filter
The binary filter enables you to remove small white or black noise along the
gage. This filtering function can be useful if noise prevents you from getting
stable edges, and/or you want to reduce or eliminate unwanted edges. If so,
you can pick the field next to “
Filter ” in the tool edit panel. When you do,
the Binary Filter panel appears, as shown in Figure 8.3 (page 8–4).
