morph_hat — MV `morphology` op

• Data kinds: mask × mask → mask

• Call: import fullseye as fs; fs.ledger.morph_hat(region, se) (to call the implementation directly, import mvmorph; mvmorph.morph_hat(region, se); from the registry, opsmv.get("morph_hat"))

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

• GPU: none (CPU reference implementation only)

Usage

Return the union of the pixels removed by opening and the pixels added by closing.

画像の外は背景と見なす。空の入力(region が 0 要素)は ValueError。

Args:

region: 2-D の領域。

se: 構造要素(奇数辺の bool 配列)。

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.
