region op• Data kinds: region → region
• Call: fullseye.apply(img, "thinning_golay", a=0.5, b=0.5) (the 2-D model is one image plus two scalar knobs a,b∈[0,1])
• HALCON equivalent: thinning_golay (the HALCON reference is a useful guide to its meaning and parameters)
Thins a region. The implementation uses skimage's `thin` (Guo-Hall-type iterative thinning), repeated until the region is completely 1 pixel wide; a and b are unused.

HALCON の `thinning_golay`(Golay アルファベットの構造要素を使ったヒット・オア・ミス変換で 1 ステップぶんだけ細線化する演算、通常は反復して使う)とはアルゴリズムも粒度も異なる近似 —— 単一ステップではなく収束するまで細線化してしまう。
