gauss_filter — 2D `smoothing` op

• Data kinds: image → image

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

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

Usage

> This operator's description has not been translated yet. The original text follows as it is.

ガウシアンぼかし(`scipy.ndimage.gaussian_filter、シグマ 0.3+2.7*a`)

による平滑化。HALCON の `gauss_filter`（Smooth using discrete Gauss

functions.）の代役 ―― HALCON は離散ガウス核(整数演算)、こちらは連続ガウス核

の scipy 実装で、近似ではあるが結果は非常に近い。

`a がシグマを 0.3〜3.0 の範囲で振る。b` は未使用。実装は

`gauss_image` と同一。

• 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.
