ABSTRACT:
Each of a certain number of sequences of binary pixels chosen according to some prescribed rules from m.times.n matrix of pixcels is referred to vector v.sub.i. A standard character k is represented with m.times.n matrix of binary pixels, from which the vectors g.sub.ki are derived. The reference vectors G.sub.ki are comprised of the vectors g.sub.ki and g.sub.ki which are generated by modification of g.sub.ki. A recognition object is captured to yield m.times.n matrix of binary pixels, from which the vectors v.sub.i are derived for comparison with the reference vectors G.sub.ki. Matching of v.sub.i with one of the reference vectors G.sub.ki adds a count to the standard pattern k corresponding to G.sub.ki. The standard character k with the maximum score of the matching count is recognized as the recognition object.
