extra op• Data kinds: image → region
• 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])
Binarization by the moment-preserving method (SimpleITK `MomentsThreshold`, Tsai's method). Selects the threshold so that the statistical moments (mean, variance, etc.) of the binarized histogram match those of the original histogram.

`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。
