Abstract

Segmenting brain magneticnresonance (MRI) images ofrthe brain into white matter (WM), grey matter (GM) and cerebrospinal fluid (CSF) is an important problem in medical ima e analysis. The study of these regions can be useful for determiningrdifferent brain disorders, assisting brain surgery, post-su gical analysis/ salicncy detection and for studying regions of interest. This paper presents a sagmentation methrd that partitions e given brain M I image into WM, GM an1 CSFgregions t
