landmark_asymmetry — SHAPESTAT `symmetry` op

• Data kinds: points → signal

• Call: import shapestats; shapestats.landmark_asymmetry(landmarks, pairs=None, plane=None) (or opsshapestat.get("landmark_asymmetry"))

Usage

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

左右の対ごとの符号つき非対称量。→ `(M,)`。

各対について、片方を面で鏡映してもう片方と比べ、面の法線方向の差を返す。

符号は「右が外側なら正」(:func:mirror_plane_from_pairs が法線をその向きに

揃えている)。絶対値にまとめない —— 左右どちらが張り出しているかは

臨床でも検査でも意味が違う。

`pairs=None / plane=None はどちらも :func:mirror_plane_from_pairs`

と同じ既定(前半/後半の対、その対から出した正中面)。**面を省くと、面自体が

同じ対から決まる**ので「面を決めた材料で面からのずれを測る」ことになる ——

それでも左右差は測れる(中点は定義上どちらの側にも寄らない)が、

別の情報源から面が決まるなら渡したほうが強い。
