-// Description: This program executes the Isodata unsupervised
-// classification - clustering algorithm. Isodata
-// stands for Iterative Self-Organizing Data Analysis
-// Techniques. This is a more sophisticated algorithm
-// which allows the number of clusters to be
-// automatically adjusted during the iteration by
-// merging similar clusters and splitting clusters
-// with large standard deviations.
