thinning — 2D `region` op

• Data kinds: region → region

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

• HALCON equivalent: thinning (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.

`skimage.morphology.thin`(Zhang-Suen 系の細線化アルゴリズム)による

1 画素幅化。`skeleton` と目的は似ているが内部アルゴリズムが異なるため、

分岐点周辺などで結果がわずかに違うことがある。HALCON の `thinning`

（Remove the result of a hit-or-miss operation from a region.）の代役。

`a, b` は未使用。skimage が無い環境ではこの分岐は呼べない。

References (sample data, literature)

• Sample-data catalog (download URLs / licences) — 2-D uses skimage.data (BSD/public domain) plus synthetic images; 3-D lists download URLs for real data sources (Stanford, PDS, …).

• Operator provenance and references — the sources of the research/methods this op family came from.

• The canonical algorithm (author, year) and its uses are named in the family usage guide above.
