The labels of the nodes of INeN are determined before the segmentation process. A usage counter
is assigned for each node. The counter of the nearest node to the input vector is increased by one. A
histogram, which shows the usage frequency of nodes, is formed. If the counter of the node is higher
than a predefined value, a label is assigned to this node. This constant value is selected by a user,
and it determines the number of labels. Each node is labeled with a different label, and represents only one class. The nodes, which have a counter with a low value, are removed from the network.
