MRI brain image segmentation based on point symmetry distance - fuzzy C means algorithm

BACKGROUND： Image segmentation is a significant step of image processing and analysis. Within the traditional segmentation methods, fuzzy C means clustering （FCM） is applied widely. OBJECTIVE： To introduce point symmetry distance （PS）-FCM （PS-FCM） algorithm into the MRI brain image segmentation so as to promote the accuracy of MRI image segmentation. METHODS： In connection with the traditional FCM algorithm based on Minkowski distance, this pepper introduces PS-FCM algorithm into the MRI brain image segmentation. RESULTS AND CONCLUSION： Experimental results show that PS-FCM has obvious advantages compared with traditional FCM algorithm.
