Figure 240. Edge Strength Threshold—Edge
Profile
Graph
For edge strength threshold, the x axis is the length of the ROI. The y axis has two measurements. The
first
is the light blue axis. It
represents Edge Strength, a measure of the rate of change of pixel grayscale values. The second is the dark gray axis. It represents Edge
Profile,
which gives the absolute grayscale level across the tool ROI. The blue line is the rate of change of the grayscale value along the
ROI. The two horizontal gray lines are the edge strength threshold plus and minus.

Smoothing
Runs a rolling average along the ROI length. Smoothing
filters
out sharp changes in the edge
profile.
Object Width
Filters out objects and spaces that are smaller than the minimum and larger than the maximum values
specified.
Enable End Objects
When enabled, pixels that touch the ends of the ROI are ignored. This may ignore one or more objects.
