ABSTRACT
This paper presents a novel hybrid segmentation technique
incorporating a statistical as well as a geometric model in a
unified segmentation scheme for brain tissue segmentation
of magnetic resonance imaging (MRI) scans. We combine
both voxel probability and image gradient and curvature
information for segmenting gray matter (GM) and white
matter (WM) tissues. Both qualitative and quantitative
results on synthetic and real brain MRI scans indicate
superior and consistent performance when compared with
