Figure 1.
An example of an MR image in the OASIS database.
(a) A sagittal section, with the front (anterior) of the head at the right and the top of the head shown at the top. This orientation shows an image as if the subject were being viewed from the right. (b) A coronal section, with the top (superior) of the head displayed at the top and the left shown on the left. This orientation shows an image as if the subject were being viewed from behind. (c) An axial section, with the front (anterior) of the head at the top and the left shown on the left. This orientation appears as if the subject were being viewed from above.
Figure 2.
The distributions of correct and incorrect matching scores.
The vertical axis represents the distribution of matching scores as a percentage. (a) The distribution of matching scores in the ‘Same-Visit’ experiment. (b) The distribution of matching scores in the ‘Different-Visit’ experiment.
Figure 3.
The ROCs of the matching experiments.
The solid line (pink line) represents the ‘Same-Visit’ experiment, while the dashed line (black line) represents the ‘Different-Visit’ experiment.
