Definition of the set of features constructed in Ex 2, with regard to the representation of a focal voxel at s

Symbol	Meaning	Count	Scope
ms,l,t	Microstructure value of voxels at a neighbor level l, with index t, of a focal voxel at s	179	Binary, {0,1}
	l=1,…,12
${\text{pr}}_l^h$	Fraction of voxels with microstructure phase h at neighbor level l	24	Real, [0,1]
${\text{pr}}_l^h$	Fraction of voxels with microstructure phase h up to neighbor level l	24	Real, [0,1]
$I_{\text{norm}}^h$	The normalized impact of all 12 levels of neighbors of phase h	2	Real
	$I_{\text{norm}}^h=\sum _{i=1}^{12}{T}_l·{\text{pr}}_l^h/\sqrt{l}+T_0·{\text{pr}}_0^h/0.5$
S 3	3-plane symmetry index	1	Real
S 9	9-plane symmetry index	1	Real
