xkor_hessian — 2D `edges` op

• Data kinds: image → image

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

Usage

Blob/corner response based on the Hessian matrix. Calls `kornia.feature.hessian_response` with default parameters, takes the absolute value, and normalizes by the maximum absolute value.

a, b は未使用（共通ヘルパー `_resp` が a, b を受け取るだけで捨てる）。

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.
