tb_euclidean_cluster — 2D `typed` op

• Data kinds: points → volume

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

Usage

Distance-based clustering via the connected components of a proximity graph with radius tol (-1 = noise).

互いに `tol` 以内の点を(推移的に)同一クラスタへ束ねる。空間的に離れた物体が

別クラスタになる(接地面除去後の「どの塊が掴める物か」の分離に使う)。連結成分のうち

`min_size` 未満のものはノイズとして -1。ラベルはクラスタサイズ降順で 0,1,2,...

(決定論)。

Args:

points: (N,3) 点群。

tol: 同一クラスタとみなす近接半径(距離、要 > 0)。

min_size: これ未満の連結成分はノイズ(-1)。

Returns:

labels: (N,) int。0..(n_clusters-1) がクラスタ、-1 がノイズ。空入力は shape (0,)。

2-D 進化レジストリへ橋渡しした 3d の op `euclidean_cluster。実装は同じで、呼び出し規約だけ op(v, a, b) に合わせてある。a が min_size(既定 10)を振る。b` は未使用。

• Operator provenance and references — the sources of the research/methods this op family came from.
