METHOD OF SELECTING CLUSTERS OF ITEMS USING A FUZZY HISTOGRAM ANALYSIS

A method and apparatus for selecting clusters of a set of data items by using a histogram. This method includes receiving item data including coordinates of a metric space; dividing the metric space into a plurality of bins; associating a distance from at least a particular coordinate to each of the item data; inserting each of the item data into a bin within the distance of the item data so as to generate a histogram and, using the histogram to obtain one or more clusters.
