transpose_region — 2D geometry op

Data kinds: regionregion

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

HALCON equivalent: transpose_region (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.

領域(2 値マスク)を転置する(`x.T`、対角線に関する鏡映=行と列の

入れ替え)。カテゴリは geometry だが in/out は `region`。幾何変換の一種

として `_sh_geom` で実装されているが、転置は補間を伴わないため

`build()_rebinarise` を通しても値は変化しない(すでに {0,1} の

まま)。HALCON の `transpose_region`(Reflect a region about a point.)に

相当(HALCON の「点に関する反転」とは厳密には別の変換で、行列の転置=

対角線に関する反転という近似)。

`a, b` は未使用。
