xsitk_confidence_connected — 2D extra op

Data kinds: imageregion

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

Usage

Confidence-connected region growing (SimpleITK `ConfidenceConnected`). Uses the image center as a seed, builds an interval of 'mean +/- multiplier * standard deviation' from the mean and standard deviation of the current region, and expands the connected region while iteratively updating this interval (a more statistical way of choosing the threshold than xsitk_connected_threshold).

> The detailed description below is the original text — the summary and the headings are translated.

`a は反復回数(1+int(a*5) で 1〜6)、b は標準偏差の倍率(1.0+3.0*b` で 1〜4)を振る。初期近傍半径は 2 固定。画像中心付近に対象があることを前提とした op。
