Brain tumor segmentation from multimodal magnetic resonance images via sparse representation

作者:

Highlights:

• An automated brain tumor segmentation model based on maximum a posteriori probabilistic (MAP) estimation is presented.

• The likelihood probability of the model is estimated by sparse coding and dictionary learning.

• The Markov random field (MRF) is introduced into the prior probability.

• The MAP is converted into a minimum energy optimization problem and graph cuts is used to find its solution.
