With no need of a prior knowledge about the tissue intensity or anatomical information, the supervised hybrid classifier was utilized for tissue classification of multispectral MRI in the native coordinate space by using only one small set of training samples. The preliminary results demonstrated that the proposed method can perform an accurate and reproducible brain volume morphometry of multispectral 3D high spatial resolution MRI in synthetic image data and in different groups of human subjects. This supervised method has shown potential in clinical applications, particularly promising for longitudinal studies of brain morphometry with multispectral MRI.
