This paper presents the implementation and quantitative evaluation of a multiphase three-dimensional deformable model in a
level set framework for automated segmentation of brain MRIs. The segmentation algorithm performs an optimal partitioning
of three-dimensional data based on homogeneity measures that naturally evolves to the extraction of different tissue types in
the brain. Random seed initialization was used to minimize the sensitivity of the method to initial conditions while avoiding
