scientific image processing, segmentation, and registration.  Segmentation is
the process of identifying and classifying data found in a digitally sampled
representation.  Typically the sampled representation is an image acquired
from such medical instrumentation as CT or MRI scanners.  Registration is the
task of aligning or developing correspondences between data.  For example, in
the medical environment, a CT scan may be aligned with a MRI scan in order to
combine the information contained in both.")
