halcon_ext op• Data kinds: image → feature
• Call: fullseye.apply(img, "hx_fuzzy_measure_pairs", a=0.5, b=0.5) (the 2-D model is one image plus two scalar knobs a,b∈[0,1])
• HALCON equivalent: fuzzy_measure_pairs (the HALCON reference is a useful guide to its meaning and parameters)
*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).*
Count edge pairs along the central horizontal profile (the rising boundary of a bright bar to its falling boundary) — 1-D metrology.

レベル閾値の交差で境界を 1 回ずつ取る(np.gradient はステップを 2 画素に滲ませ二重計上
するため不可)。閾値 lvl は a で可変。返り値は対の数(/10 で正規化した feature)。

• 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.
The program below has been verified to run (same input as the figure). In Studio's help this block becomes buttons that load and run it on the spot.
