sg_region_growing_seeded — 2D `segment` op

• Data kinds: image → region

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

Usage

Seeded region growing that starts from the image centre and connects pixels with similar intensity (HALCON `regiongrowing is already covered by another op, so halcon=""` is used here to avoid double-reporting it).

種は画像中心の 1 画素。`a（0〜1）が同質性の許容差（種の輝度 ±a 以内なら繋がる）、b が連結性を切り替える（b > 0.5` で 8 連結、それ以外は 4 連結）。結果は種を含む連結成分のみ。
