sk_lbp — 2D `texture` op

• Data kinds: image → image

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

Usage

LBP (Local Binary Pattern). A texture descriptor robust to illumination changes, built by comparing each pixel to its neighbors on a surrounding circle to form a binary code.

HALCON に直接対応するものは無い。実装は `feature.local_binary_pattern(v, 8, 1+int(a*3)) を正規化したもの —— 近傍点数 P=8 は固定、a は半径 R を 1〜4 に振る(半径が大きいほど粗いスケールのテクスチャを拾う)。b は未使用。method は既定の 'default'`(回転不変ではない、最も基本的な符号化)。

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.
