sub_image — 2D `nary` op

• Data kinds: image × image → image

• Call: this op takes 2 inputs, so fullseye.apply cannot run it (that is the one-image model). g = fullseye.FullseyeGraph(); g.add("out", "sub_image", ["$in1", "$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: sub_image (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 枚の画像を減算する。HALCON の `sub_image に相当。out = clip((I1 - I2) * (0.5 + a) + b, 0, 1) —— 負になる差を b で持ち上げないと 0 に潰れる(既定 b=0.5` で中央値が灰色になる)。
