Classification of the CSF, GM, and WM tissues by performing TRIOA, SPM8-N-m, SPM12-m, and FAST-m on the brain images of three age groups. (a) T1WI, T2WI, and FLAIR MR images of young adults (30 years old); (b) T1WI, T2WI, and FLAIR MR images of middle-aged adults (51 years old); (c) T1WI, T2WI, and FLAIR MR images of elderly adults (66 years old); (d) results obtained using TRIOA on the original MR images presented in each group; (e) results obtained using SPM12-m on the original MR images presented in each group; (f) results obtained using SPM8-N-m on the original MR images presented in each group; and (g) results obtained using FAST-m on the original MR images presented in each group.
