Figure 8.13:
Impact of the intensity correction for the non-rigid registration.
Top row: the images to be registered. Middle row: The source image is registered
toward the target image, without intensity correction (left) and with correction
(right). Bottom row: the differences images show the relevance of the intensity
correction on the non-rigid registration.
errors: the first one is the registration error which comes from the anatomical
variability that we could not apprehend. The second error is due to the difference
of acquisition of the two volumes, which makes the histograms of the source
and target volumes different.
