intersection — 2D nary op

Data kinds: region × regionregion

Call: this op takes 2 inputs, so fullseye.apply cannot run it (that is the one-image model). g = fullseye.FullseyeGraph(); g.add("out", "intersection", ["$in1", "$in2"], a=0.5, b=0.5); g.run({"$in1": img1, "$in2": img2}, terminal="out") (names starting with $ are the inputs you pass in)

HALCON equivalent: intersection (the HALCON reference is a useful guide to its meaning and parameters)

Usage

> This operator's description has not been translated yet. The original text follows as it is.

2 つの領域の積(両方に入る画素)。HALCON の `intersection に相当。入力は > 0.5 で二値化する。a, b` は未使用。
