摘要：Method and device for recognizing characters, in which in a learning phase, aswell as in a subsequent working phase features of character patterns in a number ofaspects thereof are classified in a number of groups. During the learning phase theresults of these classifications are recorded in a store as statistic frequencies. During theworking phase the result of the feature classification of a freshly offered character isutilized in determining, for each class of characters, (a) the probabilities of the featuresfound in this character, and (b) the weight of the features of a character pattern to berecognized. The weight attributed to each feature depends upon the shape of thepattern, and upon the basis of the values of these weights, the features are selected. Thestored statistic frequencies of the selected features are multiplied by the values of theweights, and the largest value among the results is utilized for indicating the class of thefeature. Thus from the selected classes of features, the character is determined.
