xmh_daubechies — 2D transform op

• Data kinds: image → image

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

Usage

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

Daubechies ウェーブレット変換(`mahotas.daubechies`)。xmh_haar と同じ配置(1 段、係数を元画像サイズの配列に詰めて min-max 正規化)で、基底を Daubechies 系に変えたもの。

`a はウェーブレットの種類を D2/D4/D6/D8 の 4 択で切り替える(タップ数が増えるほど滑らかで長いフィルタになる)。b` は未使用。

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.
