+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.")
