Simulation study I on a T-junction shaped surface where three black signal regions of different sizes are taken as the ground truth. 60 independent functional measurements on the T-junction were simulated as |N(0, 22)| at each mesh vertex. We are only simulating positive numbers to better reflect the positive measurements used in the study. Value 1 was added to the black regions in 30 of measurements which served as group 2 while the other 30 measurements were taken as group 1. T-statistics are shown for these simulation (original) and three techniques with bandwidth 0.5. Heat kernel smoothing performed the best in detecting the ground truth.
