Box plot of the nRMSE between registered and ground truth volumes in the synthetic data experiments. The mean error due to alignment before registration is 2.67 in normalized units. Registration reduces the difference to 1.514 for LiMo-MoCo, 1.519 for REFVOL and 1.632 for gPCA. Both LiMo-MoCo and REFVOL attained the smallest nRMSE of the registered images.
