An extension of the histogram-based fast FCM to EM algorithm is presented in this paper for the segmentation of multi-spectral MRI, with the basic idea of contextual constrains applied. The combination provided a faster and more liable method compare to conventional MRI segmentation using EM to find maximum likelihood mixture densities parameters.
