Brain MRI Segmentation Using an Expectation-Maximization Algorithm
Koen Van Leemput · 2003
MRF model tends to minimize the boundary length between tissuesThis discourages classifications from accurately following the complex shape of the tissue interfacesMRF over-smooths the classifications in cases where the intensity information doesn't prevent itIn order to solve this, better spatial models are needed to describe the spatial distribution of tissues in the brain
