| Abstract: | Application of fuzzy C-means（FCM） algorithm is studied to brain MRI image segmentation. The deficiencies of traditional FCM algorithm are introduced, and the improvement is explored from the aspects of spatial continuity and magnetic field nonuniformity correction, kernel-based FCM algorithm as well as co-segmentation by FCM and other algorithms. The improvement of the traditional FCM algorithm is described, and it＇s pointed out that FCM algorithm has to be enhanced for the objective function and combined with other algorithms. |
