The computational procedure of the gray/white matter boundary (GWB) width map.

Method: LDPO Method

Input: Gray Scale Image Y

Output: GWB Width Map D

Segment Y and find the parameters of GM, WM and CSF according to Equation (7) (Section Preprocessing). Compute probability images of GM, WM and CSF according to Equation (10) (Section Preprocessing). Label regions of interest according to Equation (11) (Section LDPO for GWB Width Estimation). Generate local directions through solving Laplace Equation on GWB region according to Equation (13) (Section LDPO for GWB Width Estimation). Find the optimal corresponding voxels in WM and GM for each voxel on GWB according to Equation (15) and Equation (16) (Section Evaluations). Measure the width (Equation 1) according to the optimal corresponding voxels in WM and GM (Section Datasets and Ground Truth).
