vol_dilate — 2D 3d op

Data kinds: volumevolume

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

Usage

Grayscale dilation of a 3D volume. No corresponding HALCON op is specified.

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

`_vol_erode と同じ式 size = 1 + 2*(1 + int(a)) を使うため、a はほぼ効かない(a[0,1) の間は int(a) が常に 0 で実質サイズ 3 固定、a=1.0 のときだけ 5)。b も未使用。半径を連続的に振りたい場合は球形構造要素版(_vol_dilation_ball 等、int(a*3) を使い a` が実際に効く)を使うこと。
