xsk_sato — 2D `texture` op

• Data kinds: image → image

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

Usage

> This operator's description has not been translated yet. The original text follows as it is.

Sato tubeness フィルタ。skimage.filters.sato をスケール sigma=1,2,3 の 3 段で

適用し、管状構造(血管など)を強調する。ヘッセ行列の固有値比から線状/管状

らしさを計算する点は `xsk_meijering` と同系だが、応答の重み付けが異なり

分岐点には Meijering ほど強く応答しない。

`a, b は未使用(sigma は固定)。出力は _norm` で正規化した符号なし

強度画像。

• 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.
