 == Summer Project Week Breakout Session: Registration for EM Segmenter ==
-Tuesday June 21, 2011, 3-4pm,  Star room.
+Wednesday, June 22, 2011, 3-4pm,  Star room.
 ====Synopsis: ====
 The EM segmenter includes as a vital step the co-registration of a multiple subject atlas to obtain spatial priors for small region detection. The success of these priors depends heavily on the quality of the registration obtained.  Because the registration includes a large-DOF nonrigid inter-subject registration, benchmarks for a good solution are largely absent.  We seek an implementation of a registration using Slicer registration tools that will provide best possible robustness and if possible an estimate of reliability.  Because this registration will be integrated into a slicer module, tools with a BSD license are strongly preferred.
