The box plots of the correlation values in our method and the TDFFD method for the baseline, IVC occlusion, and LAD ligating cases. The bottom and top box boundary and the center line show the first quantile, third quantile, and median, respectively. The ends of the whiskers show the minimum and maximum of each case. For each dataset in each method 30 correlation values are averaged, except the six diagonal correlation value which is one.
