Sum of weights (i.e., ∑ 4 j = 1 b j ) on MRI data. The vertical axis represents the percentage that the estimation values of ∑ 4 j = 1 b j lies in the corresponding values in the horizontal axis. a-b list the frequency of ∑ 4 j = 1 b j for simulated images (i.e., Fig. 3a and b). c-d list the frequency of ∑ 4 j = 1 b j for real images (i.e., Fig. 9a and b)
