ABSTRACT:
A pattern matching apparatus for comparing an input pattern of features with a reference pattern. Address information is stored in the reference pattern along with features, so that branching in a work memory which stores cumulative distances between the input and reference patterns may be effected. In this manner, memory requirements for storing reference patterns are reduced, and the number of required distance calculations also is reduced.
