FIG. 2.

Example landmarks annotated by human experts in a representative patient (patient #1). Landmarks with the same indexing numbers in different images correspond to each other, according to the expert annotations. Note that the images have been manually cropped for the display purpose. In the automated registration, however, we used the entire images as shown in the first rows in Figs. 7 and 8, where no manual or automated cropping was involved.
