TABLE I.

Map Features of the Final Map Generated With Every Method for All Subjects. The Ground Truth Values Are Shown in the Column Labeled GT. The Columns Show Both Experimental (Left) and Computational (Right) Results. Units Are Given for S1 and Are Identical for Each Feature for the Other Subjects. The Group Mean and Standard Deviations for Volume and Area Are Shown at the Bottom
