Figure 4

Overview of the postprocessing step depicted in 2D for clarity. From the averaged volume, the points with values higher than 0.5 were clustered. The largest cluster was selected, and from the points with values higher than 0.9, the centroid was computed. This centroid was used as the predicted 3D point.
