  1. Mean ± SD of nIQR values obtained for non-segmented images and images segmented by manual, OP-MIX-FCM, and SA-MIX-FCM schemes. Results are tabulated by LIC level and demonstrate that all segmentation types yield similar variations (nIQR), all of which are substantially lower than those corresponding to non-segmented images
