Results of the experiment to investigate the impact of dataset size in the source and target domains on the effect of transfer learning. In this experiment, the source task is whole brain segmentation in the Whole-Brain-MRI dataset, and the target task is brain cortical plate segmentation in the CP-newborn dataset. For each setting of the number of images in the target domain, there were no statistically significant differences in the results obtained with different numbers of images in the source domain (p = 0.05).
