get_region_thickness — 2D `features` op

• Data kinds: region → feature

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

• HALCON equivalent: get_region_thickness (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.

領域の太さの近似値 `2 × 最大内接円半径 / 最大辺長`

(`distance_transform_edt` の最大値の 2 倍を画像サイズで正規化)。HALCON

の `get_region_thickness`（Access the thickness of a region along the

main axis.）が定義する「主軸に沿った太さのプロファイル」とは異なり、

方向を問わないグローバルな最大内接半径だけを見る単純化(主軸方向の情報は

失われる)。

`a, b` は未使用。

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.
