world_blobs_touching — SEGMENTATION `world` op

• Data kinds: none → table (an op determined by its arguments alone — it takes no image or data input)

• Call: import fullseye as fs; fs.ledger.world_blobs_touching(n: 'int' = 10, overlap: 'float' = 0.2, seed: 'int' = 0, *, size=(160, 160), radius: 'float' = 14.0, noise: 'float' = 0.03) -> 'Dict[str, object]' (to call the implementation directly, import segworld; segworld.world_blobs_touching(n: 'int' = 10, overlap: 'float' = 0.2, seed: 'int' = 0, *, size=(160, 160), radius: 'float' = 14.0, noise: 'float' = 0.03) -> 'Dict[str, object]'; from the registry, opssegmentation.get("world_blobs_touching"))

Usage

World of overlapping discs (cells/grains): equal-radius circles placed in a chain, each overlapping only the previous one at centre distance 2r(1 - overlap) (world_blobs_touching).

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

ラベル = 円の内側で最も近い中心(重なりは垂直二等分線で分ける)。画像 = 明るい内部 + 暗い縁 + 重なりはやや明るい

+ ぼかし + 雑音(細胞の見た目)。鎖がそれ以上伸ばせなければ新しい鎖を始める(その円は誰とも重ならない)。

返り値: `image、labels、count_map(各画素を覆う円の数)、truth = {n、centers (n, 2) [y, x]、radius`、

`overlap、pairs (m, 2)(重なる組)、lens_area (m,)(閉形式)、areas (n,)(πr² − Σ レンズ/2)、union_area`、

`overlap_measured`(2 つ以上に覆われた画素 / 和集合の画素)}。置けなければ ValueError。
