macro_binarize — 2D macro op

Data kinds: imageimage

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

Usage

A fixed pipeline discovered by evolutionary search: `bilateral(a=0.06,b=0.89)unsharp(a=0.51,b=0.34)bilateral(a=0.04,b=0.24)lowpass(a=0.75,b=0.59)gopen(a=0.38,b=1.00)unsharp(a=0.78,b=0.68)` (6 stages that alternate smoothing and unsharp masking, clean up with a lowpass and grayscale opening, then sharpen once more).

`a, b` は凍結済みで未使用。binarize 課題(IoU)でロック済みホールドアウト 0.75、手作りベースライン 0.62 を上回るが、train 0.91 / holdout0.95 に対し locked_holdout は 0.75 まで落ちる —— 分割ごとの差を隠さず書く(feedback_benchmark_honest_disclosure)。HALCON に対応する単一オペレータは無い。

References (sample data, literature)

• 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.
