thickening_seq — MV `morphology` op

• Data kinds: mask → mask

• Call: import fullseye as fs; fs.ledger.thickening_seq(region, letter, iterations=0) (to call the implementation directly, import mvmorph; mvmorph.thickening_seq(region, letter, iterations=0); from the registry, opsmv.get("thickening_seq"))

• HALCON equivalent: thickening_seq (the HALCON reference is a useful guide to its meaning and parameters)

• GPU: none (CPU reference implementation only)

Usage

Thicken a region through the rotations of a Golay letter in turn until it stops changing.

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

letter="c" は 90 度ずつ 4 回転で凹の角を埋め、4 連結の領域は外接矩形へ収束する(斜めの階段も凹の角の並びなので全部埋まる。凸包ではない)。iterations が 0 なら収束まで。空の入力(region が 0 要素)は ValueError。

Args:

region: 2-D の領域。

letter: Golay の文字。

iterations: 全回転を掛ける回数の上限(0 は収束まで)。

Returns:

region と同じ形の bool 配列。

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.
