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

*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).*
Harris corner response. Calls `kornia.feature.harris_response and maps the signed response to [0,1] with signed01` (keeping the sign information of the Harris response - positive for corners, negative for edges - while fitting it into a visualizable range).

a が Harris のスコア係数 k(`0.04 + 0.02 * a`、経験的に 0.04〜0.06 の範囲で使われる値)を振る。b は未使用。

• 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.
