ABSTRACT:
For the preparation of a tree structure recognition dictionary, a feature set at each node of the tree should be the feature giving the largest discrete distribution number. When elements of an object are classified or divided into categories, if the number of combinations of subgroups, which are discrete, is the largest, the classification is the most effective. This classification is effected, when the distance between distributions for a certain feature is larger than a predetermined value.
