PARAFAC analysis of the three-dimensional tongue shape

Abstract: this paper is to demonstrate that PARAFAC successfully represents thethree-dimensional shape of the tongue surface extracted from coronal magnetic resonance(MR) image stacks. Two types of measurement vectors are analyzed: a vector of 3Dpseudo-fleshpoint coordinates extracted uniformly from the length and width of thetongue surface, and a vector of 2D pseudo-fleshpoint coordinates extracted from a curvealong the tongue surface close to the midsagittal plane. The 2D pseudo-fleshpoint...
