Abstract
An optical character reading system first determines the height and width of the character to determine its authenticity and then examines the features of each line and/or column and classifies each line or column according to its pattern. The sequence in which the classification numbers occurs is indicative of the character detected. Correction of oblique scanning and direction determining features are also included.
