shape_synth_family — SHAPESTAT `synth` op

• Data kinds: none → shapeset (an op determined by its arguments alone — it takes no image or data input)

• Call: import shapestats; shapestats.shape_synth_family(n_shapes: 'int' = 8, n_points: 'int' = 64, n_modes: 'int' = 2, mode_scale=(0.3, 0.12), noise: 'float' = 0.0, seed: 'int' = 0) (or opsshapestat.get("shape_synth_family"))

Usage

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

既知の変形モードを持つ形の群を作る。→ `(n_shapes, n_points, 3)`。

基準形は楕円体上の準一様な点で、そこに 正規直交な変形モードを

既知の重みで足す。モード 1 は長軸方向の伸び、モード 2 は左右の曲げ。

:func:shape_pca に食わせると、**主成分の分散比が `mode_scale` の 2 乗比に

一致する**はずで、これが統計形状モデルの検算になる。

`noise` は点ごとの等方ガウス雑音の標準偏差(モデルに乗らない成分)。
