Fig. 5From: Semi-automatic measurements of foot morphological parameters from 3D plantar foot scansReference volume for nAVI normalization. Left, the base of the reference volume, where b1/3 and b2/3 are the widths of the 3D foot scan at 1/3 and 2/3 of LTE. Right, the reference volume superimposed to the foot; the height of the reference volume is α*LTE (see Eqs. 1 and 2)Back to article page
