DTI (Diffusion Tensor Imaging) is a well-known MRI (Magnetic Resonance Imaging) technique which provides useful structural information about human brain. However, the quantitative measurement to physiological variation of subtypes of ischemic stroke is not available. An automatically quantitative method for DTI analysis will enhance the DTI application in clinics. In this study, we proposed a DTI...
K-means algorithm is a popular method in clustering analysis. After reviewing the traditional K-means algorithm, we proposed an improved K-means algorithm. At first we select the Euclidean distance or Manhattan distance as distance measure in our algorithm through calculating the rule of distance measure. Different initial centroids lead to different results. So the next step we will select the initial...
