xkor_median — 2D `rank` op

• Data kinds: image → image

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

xkor_median: 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

Median filter. Calls `kornia.filters.median_blur`.

a でカーネルサイズを 3/5/7/9 の 4 段階から選ぶ

（`(3,5,7,9)[min(3, int(a*4))]`）。b は未使用。ごま塩ノイズなど

外れ値ノイズに強く、ガウシアンぼかしよりエッジを保ちやすい。

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.
