segmentation op• Data kinds: image → region
• Call: fullseye.apply(img, "xsk2_h_maxima", a=0.5, b=0.5) (the 2-D model is one image plus two scalar knobs a,b∈[0,1])
h-maxima transform (removes local maxima with a height less than h). Calls `skimage.morphology.h_maxima`.
> The detailed description below is the original text — the summary and the headings are translated.
a が高さのしきい値 h(`0.05 + 0.3 * a`、範囲 0.05〜0.35)を振る。
b は未使用。出力は極大が残った画素を 1 とする二値画像(region)。
h が小さいほど微小なノイズ状の極大まで拾い、大きいほど際立った山だけ
残る。
