morph_skeleton — 2D `region` op

• Data kinds: region → region

• Call: fullseye.apply(img, "morph_skeleton", a=0.5, b=0.5) (the 2-D model is one image plus two scalar knobs a,b∈[0,1])

• HALCON equivalent: morph_skeleton (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.

領域の骨格線（スケルトン）を抽出する。実装は skimage の `skeletonize`（Zhang–Suen 型の反復細線化アルゴリズム）で、a, b は未使用。

HALCON の `morph_skeleton`（構造要素による反復収縮とその差分から求める形態学的スケルトン）とはアルゴリズムが異なる近似 —— 同じ「1 画素幅の骨格」という結果を目指すが、生成過程・端点の扱いなどが morph_skeleton の定義と一致するとは限らない。
