Brain Tissue Segmentation via MRI
 
Suyash P. Awate, Tolga Tasdizen, Normal Foster, Ross T. Whitaker
Adaptive Markov modeling for mutual-information-based, unsupervised MRI brain-tissue classification
Medical Image Analysis 2006, 10(5):726-39

Challenges
1) noise
2) oversmoothing in cortex
3) field inhomogeneity
4) partial-volume effects

Our Approach
1) Markov random field model on data; inferred nonparametrically
2) avoid explicit label regularization
3) spatially-adaptive tissue modeling
4) nonparametric modeling

Results

Handling noise

solid line = our method

Handling bias / inhomogeneity / nonuniformity


Validation for segmenting tissues

Validation for delineating the inner cortical-surface
