The invention relates to a
brain MRI (magnetic
resonance image) segmentation method based on an improved fuzzy C-means clustering
algorithm. The method comprises steps that 1, initial classification is carried through utilizing the fuzzy C-means clustering
algorithm; 2, the clustering quantity c, a fuzzy factor m, an
algorithm iteration stop threshold Epsilon, the maximum iteration times max, a neighborhood window size and other artificial setting parameters are given; 3, a
similarity matrix W of two pixels is calculated; 4, similarity rhoki of
pixel pair types is calculated; 5, a membership matrix U is updated; 6, if ||U(t+1)-U(t)||<Epsilon, or t=max, iteration stops, U(t+1) is outputted, otherwise t=t+1, and the process turns to the step 4; and 7, for U(t+1), the maximum membership algorithm is employed to carry out
deblurring operation, and
label distribution is carried out to accomplish
image segmentation. Through the method, three-portion optimization including improving a clustering center mode, introducing the partial space information and utilizing the
intuitionistic fuzzy set information is accomplished, effects of
noise resistance enhancement and segmentation precision improvement are realized, and an actual problem of high-precision segmentation for a
brain MRI is solved.
