xsitk_moments_thresh — 2D extra op

Data kinds: imageregion

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

Usage

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

モーメント保存法による二値化(SimpleITK `MomentsThreshold`、Tsai の方法)。二値化後のヒストグラムの統計モーメント(平均・分散など)が元のヒストグラムのものと一致するように閾値を選ぶ。

`a はヒストグラムのビン数(64〜256)を振る。b` は未使用。xsitk_maxentropy_thresh・xsitk_huang_thresh とは閾値選択の基準が異なるだけで、同じ入出力形。
