(invited paper from MICCAI 2005 conference)
 
Challenges Strategy
(1) noise (1) Markov random field model on data inferred nonparametrically
(2) oversmoothing in cortex (2) avoid explicit label regularization
(3) RF-field bias / inhomogeneity / nonuniformity (3) spatially-adaptive tissue modeling
(4) partial-volume effects (4) nonparametric modeling
(5) speed (5) approximations in statistical estimation:
takes 5 minutes for BrainWeb image
 
Robustness to noise and partial-volume effects
