PATTERN RECOGNITION DEVICE FOR PERFORMING CLASSIFICATION USING A CANDIDATE TABLE AND METHOD THEREOF

摘要

An object of the present invention is to speed up the calculation of a candidate category set in pattern recognition.;The candidate table 13 in the table storage means 11 receives a reference feature vector value calculated from the feature vector of the pattern as an input, and holds a mapping for outputting the candidate category set. The candidate category calculating means 12 obtains a candidate category set corresponding to a predetermined reference feature vector value by using the mapping of the candidate table 13, and outputs it.
