 The major difference between algorithms is that, in MAGeT brain, segmentations from each atlas (typically manually delineated) are propogated via image registration to a subset of the subject images (known as the 'template library') before being propogated to each subject image and fused. It is our hypothesis that by propogating labels to a template library, we are able to make use of the neuroanatomical variability of the subjects in order to 'fine tune' each individual subject's segmentation.
