hx_full_domain — 2D `halcon_ext` op

• Data kinds: image → region

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

• HALCON equivalent: full_domain (the HALCON reference is a useful guide to its meaning and parameters)

hx_full_domain: 入力 → 出力

*The figure is the real output on a synthetic 128×128 input. Left: input, right: output (a non-image return value is shown as the value itself).*

Usage

Expands the image's domain to the full image area. Corresponds to HALCON's `full_domain` (expands the domain of an image to its maximum extent).

入力と同じ形状の全 1 の region(=画像全面)を返すだけの op。ROI を絞る他の

op と対で使い、定義域をリセットするために使う。`a, b` は未使用。

• Sample-data catalog (download URLs / licences) — 2-D uses skimage.data (BSD/public domain) plus synthetic images; 3-D lists download URLs for real data sources (Stanford, PDS, …).

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

• The canonical algorithm (author, year) and its uses are named in the family usage guide above.
