xsk_flood — 2D `segmentation` op

• Data kinds: image → region

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

xsk_flood: 入力 → 出力

*The figure is the real output on a synthetic 128×128 input. Left: input, right: output (a non-image return value is shown as the value itself).*

Usage

Region extraction by flood fill.

> The detailed description below is the original text — the summary and the headings are translated.

画像中心の画素を種点とし、skimage.segmentation.flood でその画素値から

`tolerance` 以内の連結画素を region として広げる。

`a が許容差 tolerance` を 0.05〜0.35 の範囲で振る(大きいほど

広く塗りつぶす)。`b` は未使用。中心が背景か前景かで結果が大きく

変わる(種点固定の単純な実装)。

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.
