PROPOSED METHODOLOGY
Original MRI spin-density brain images; (a) gray-level image, (b) Color image
K-Means ClusteringStart
Input Data Objects
select c1,…..,ck cluster centers
Calculate distance between each pixel and each clustering center
is found
Distribute the data points x among the k clusters
Update clustering centers
Stop

Not changedFlow Chart of the K-means Clustering
Color-based segmentation with K-means clustering process for spin-density brain images ; (a)image labeled by cluster index ,(b)objects in cluster 1, (c) objects in cluster 2 ,(d) final segmentation
Morphological Filtering
