xsk2_reconstruction — 2D morphology op

Data kinds: imageimage

Call: fullseye.apply(img, "xsk2_reconstruction", a=0.5, b=0.5) (the 2-D model is one image plus two scalar knobs a,b∈[0,1])

Usage

Morphological reconstruction (reconstruction by dilation). Calls `skimage.morphology.reconstruction` with method="dilation".

> The detailed description below is the original text — the summary and the headings are translated.

シード画像を「元画像から a に応じた深さだけ暗くしたもの」

(`x - (0.05 + 0.25*a)`)として自動生成し、そのシードをマスク画像

(元画像そのもの)まで測地学的に膨張させる。a はシードの深さ(大きい

ほど多くの山が消える)を振る。b は未使用。小さな明るい斑点やノイズを

消しつつ、大きな構造の輪郭は保つ(オープニングより形状の崩れが少ない)。
