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
