These centroids should be placed in a cunning way because of different location causes different result.
the system must be fully-integrated for automated acquisition and analysis of images, including integrated 3d image analysis to enable the identification of 3d object counts, volume measurements and 3d centroids.
For managing this shifting-problem, the locations (64,64), (63,63), (63,65), (65,65), (65,63), (62,64), (64,66), (66,64), and (64,62) are used as the centroids to extract the major axis lengths, as shown in Fig.

Natural clusters that are included in the sample have the approximate centroids like the original data set.
Starts with random initial centroids and performs a re-allocation of data in different groups based on the similarity between the data object and the group centroids until a termination criterion is met, either a fixed number of iterations, or the algorithm reaches stability in the circulation of data points between groups(18).
We perform a structural analysis on the latent semantic space using the Pretopology theory that allows us to investigate the role of the number of clusters and the chosen centroids, in the similarity between the computed clusters.
