When the Y direction selected, the object counting operation will count
objects along the Y axis.
Edges
This operation configures a profile tool to count the number of “edges” in the
profile image. The edge counting is performed along either the X–axis or the
Y–axis of the image field, according to the selection in the
Direction field.
In the context of the profile tool’s edge counting operations, the term “edge”
refers to a point where the profile image intersects the threshold setting.
