“…Since the grey matter was within the border of the brain mask and in conjunction with the background, filtering the background in this method might be conducive to some false‐positive segmented pixel in grey matter tissues. A post‐processing procedure was implemented based on applying simultaneous gradient and variance windows to reduce the false‐positive results [40]. A 3 × 3 × 3 cubic window was moved onto FLAIR slices to calculate the corresponding gradient and variance features for each pixel.…”
