3-D Sato 管狀度 —— 只用兩個特徵值的更簡線狀濾波。
> 以下的詳細說明為原文 —— 摘要與標題已翻譯。
Per scale, from eigenvalues in algebraic order `e1 >= e2 >= e3` a bright
curvilinear (tube) structure has `e2, e3 < 0` and the tubeness is
`sqrt(e2 * e3) there (0 elsewhere); black_ridges=True` uses the two most
*positive* eigenvalues for dark tubes. The maximum over scales is normalised
to `[0, 1]`.
Cheaper and less selective than :func:vol_frangi (it does not explicitly
suppress plate- or blob-like structure), but a robust, well-cited tube
detector. Reference: Sato et al., Medical Image Analysis 1998.
