morphology op• Data kinds: mask × mask × mask → mask
• Call: import fullseye as fs; fs.ledger.thickening_hit_miss(region, hit, miss, iterations=1) (to call the implementation directly, import mvmorph; mvmorph.thickening_hit_miss(region, hit, miss, iterations=1); from the registry, opsmv.get("thickening_hit_miss"))
• HALCON equivalent: thickening (the HALCON reference is a useful guide to its meaning and parameters)
• GPU: none (CPU reference implementation only)
Thicken a region with an arbitrary structuring pair (A ∪ HMT(A), iterations times).

ヒットオアミスで一致した中心の画素を領域へ足す。中心はミス側に置く(ヒット側に置くと何も増えない)。変化が止まったら早く抜ける。空の入力(region が 0 要素)は ValueError。
Args:
region: 2-D の領域。
hit: ヒットの構造要素(奇数辺の bool 配列)。
miss: ミスの構造要素(同じ形)。
iterations: 繰り返しの上限(>= 1)。
Returns:
region と同じ形の bool 配列。
