synthbrain.avi: iterations of the GEN algorithm showing gradual adjustment
  of the first image's net to the second image, for the synthetic brain
  image example (fig. 2 in the paper).

toyexample.avi: as for synthbrain.avi but for a toy example (not in the
  paper).

vessel_original.avi, vessel_registered.avi: original and registered versions
  of the microscopic iris video (each frame was registered to the first frame)
  (fig. 4 in the paper). Both rigid and non-rigid deformations have been removed
  from vessel_original.avi so the white cells are more apparent and can be
  more reliably tracked.
