(A) FLAIR volume; (B) manual lesion segmentation; (C) FLAIR smoothed volume with a neighborhood n = 41; (D) FLAIR first local moment volume with neighborhood n = 5; (E) FLAIR second local moment volume with neighborhood n = 5; (F) FLAIR third local moment volume with neighborhood n = 5. The smoothed volumes act on large neighborhoods, while the local moment volumes act over smaller neighborhoods; (G) The probability map produced for the logistic regression classifier on the smoothed feature vector; (H) The scale of intensities in the probability map.
