Abstract:
1. A method for an optical character recognition (OCR) system, the method comprising: training each of a plurality of classifiers by selecting separately for each of a plurality of characters weight coefficients for a weighted mean; recognizing an input character based on the plurality of classifiers; generating from each classifier an output by comparing the input character with a plurality of training patterns; grouping the plurality of classifiers based on a classifier grouping criterion; and combining the output of each of the plurality of classifiers based on the grouping, wherein combining the output of classifiers further comprises: combining a weight output by each classifier into an interim weight in accordance with a formula for a weighted mean, using a formula for calculating the weighted mean which is selected for each character on a basis of a preliminary training process based upon the plurality of training patterns, and subsequently combining the interim weights from the calculated weighted mean with corresponding determined classifiers so as to provide a complete combined final set of weighted classifiers.
