Zusammenfassung
This paper investigates a part-based recognition
method of handwritten digits. In the proposed method
the global structure of digit patterns is discarded by representing
each pattern by just a set of local feature vectors.
The method is then comprised of two steps. First,
each of J partial patterns of a target pattern is recognized
into one of ten categories (“0”–“9”) by the nearest
neighbor discrimination with a large database of
reference partial patterns. Second, the category of the
target pattern is determined by the majority voting on
the J local recognition results. Despite the pessimistic
expectation, we have reached recognition rates much
higher than 90% for the task of digit recognition.
