texture_laws — 2D `texture` op

• Data kinds: image → image

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

• HALCON equivalent: texture_laws (the HALCON reference is a useful guide to its meaning and parameters)

Usage

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

実装は局所分散(`deviation_image` の分散版、窓内の

`E[x^2]-E[x]^2`)。本来の Laws' テクスチャフィルタは L5/E5/S5/W5/R5 などの

1 次元カーネル対から作る 25 種類の畳み込みバンク(エネルギー/エッジ/波状/

斑点/波紋を捉える)だが、この代役ではその全カーネルバンクではなく単一の

局所分散で代用している(近似の限界 ―― 方向別・周波数別の情報は失われる)。

HALCON の `texture_laws`（Filter an image using a Laws texture filter.）

の代役。

`a が窓の一辺を {3,5,7,9} で振る。b` は未使用。
