Figure 5:

Image shows synthetic dataset. Cardiac motion estimation network (CarMEN) has lower or similar transformation error relative to optimization-based methods. Predicted registration field for each method is compared against ground truth by using average end-point error and they are represented with nonparametric violin plots. Violin plots are essentially mirrored density plots. Each method is compared against CarMEN by using two-sided Wilcoxon signed-rank tests. * = P < .05, ** = P < .001; *** = P < .0001. dDemons = Diffeomorphic Demons, ITK = Insight Segmentation and Registration Toolkit.
