Fig. 2.
Line of voxels plotted over time for a sample repetition of the synthetic data experiment. Left, coronal reference image showing the line of voxels and the mask contour in red. Right, line of voxels over time for all registration methods (REFVOL, LiMo-MoCo, gPCA and No-MoCo). Overlaid, the section of the mask that corresponds to the voxels plotted. The No-MoCo panels present sharp discontinuities at the instances of motion that are corrected by the registration methods. Both REFVOL and LiMo-MoCo correctly align all the volumes, but REFVOL presents somewhat increased variability at the beginning of the sequence.
