xsk3_peak_local_max — 2D `segmentation` op

• Data kinds: image → region

• Call: fullseye.apply(img, "xsk3_peak_local_max", a=0.5, b=0.5) (the 2-D model is one image plus two scalar knobs a,b∈[0,1])

Usage

> This operator's description has not been translated yet. The original text follows as it is.

局所極大点マップ(skimage `feature.peak_local_max)。互いに min_distance` 画素以上離れた局所輝度極大の座標を検出し、その座標だけを 1 にした疎な二値画像(1 画素ずつの点で、面としての領域ではない)を返す。

`a は最小距離(2+int(a*8) で 2〜10)を振る —— 大きくするほど検出される点が減り、より支配的なピークだけが残る。b` は未使用。
