Abstract

A data acquisition control method and system for alphanumeric character recognition. An unknown pattern is normalized, the normalized pattern is then divided into top and bottom parts. A center of mass is calculated for the two parts and is utilized for vertically aligning the unknown pattern. The vertically aligned pattern is width normalized and feature vectors are obtained. The feature vectors of the unknown pattern are then compared with feature vectors of known patterns stored in memory and the characters are identified.
