Abstract

PURPOSE:To realize the recognition of a pattern with high accuracy and in a small number of standard patterns, by deciding whether or not the preprocess carried out to an unknown pattern is suited to the rule of a standard pattern and inspecting the rightfulness of the result of evaluation. CONSTITUTION:An unknown character pattern 10 is supplied to a pattern matching part 500 via an observing part 100, a thickness process part 200, a structure analyszing part 300 and a feature extracting part 400 each. Then the resemblance is evaluated between the feature quantity of the output at the part 400 and each dictionary item showing the character conception within a dictionary 900. Then a rightfulness inspecting part 600 supplies the parameter 20 sent from the parts 100, 200 and 300 each plus a pair 15 of the dictionary item number and the distance to inspect the rightfulness to each dictionary item by referring to an inhibition rule table 1,000. Thus a pair of the dictionary item number and the distance having the rejected rightfulness is disused, and only the residual pair is turned into an output 16. Then a strategy deciding part 700 has the final decision or a retrial of the recognizing process.
