Let C={[c.sub.0], [c.sub.1],..., [c.sub.k]} be the cluster centroids and D={[d.sub.0], [d.sub.1],...
Centroids and other summary information such as the number of objects and density are then calculated for the clusters.
After assigning each point [x.sub.i] to the closest cluster [c.sub.j], the centroids are re-calculated by compute the average of all points within the cluster as follows [1]:
(5) Use the modified polygon centroids from G to replace the correspondingly protected points f [member of] A, and then issue the new trajectory data I'.
On July 20, the trajectory of the sun image centroids was close to the principal point with a mean distance of 220.6 pixels.
The objective is to find a cluster assignment that minimizes the sum-of-squares loss between the samples and the corresponding centroids in the kernel space.
To establish the relationship between the individual vertebrae and the whole spine, we extract vertebral centroids as a shared feature from the segmented result.
where [X.sub.c] and [Y.sub.c] are the centroid coordinates of area-weighted suitability types, [X.sub.i] and [Y.sub.i] are the centroid coordinates of i th patch, [C.sub.i] is the area of all patches in i th suitable grade, n is total numbers of all landscape patches.
The case studies discuss some of the visualization techniques used with the tool, which primarily are - (a) Box Plot of normalized parameter variation, it helps in relatively understanding which parameters have more variation than others over the customer population; (b) Cluster Centroid Radar plot - instead of plotting individual data-file vectors, the cluster centroid vectors can be plotted on a normalized radar plot, it helps in readily understanding how the cluster centers are separated in higher dimensions; (c) Cluster Probability Distribution curves - these curves are made for each parameter by fitting normal distributions over the parameter values of individual clusters, this helps in understanding how much each cluster has an overlap over the other for a particular parameter.

Points representing nanoparticle "centroids" were then placed in the open space around the circles subject to the constraint that no point centroid could be placed inside of a circle (Figures 4(b) and 4(e)).
