Comparison of Multispectral Image-Processing Methods for Brain Tissue Classification in BrainWeb Synthetic Data and Real MR Images

Table 1

SI values for CSF, GM, and WM tissues in T1WI, T2WI, and PDW MR images using TRIOA, SPM12-m, SPM8-N-m, and FAST-m to compare the classification results of these tissues with the ground truth from BrainWeb.
