Detection result

The detection result items are shown in the table below.

[Interval]

As shown below, the interval [n] is the distance between the edge [n + 1] and edge [n]
coordinates. When setting more than one detection region, please be careful
because it differs in the case of straight line, circle, circular arc.

Line Circle

Arc

Edge dir.

Both edge

Dark -> Light

Light -> Dark

Edge strength
Min strength
Width
Target edge
Filter (sigma)

Line Circle Arc
Positional difference (only when judging by difference with master image)
Num of detect
