DOFL First Reader


schematic drawing

This is a schematic view of DOFL first reader. An unknown printed character that was to be recognized was compared to all the character sets that could contain that character, and the closest match was used to indicate the identity of the unknown character. This technique permitted the correct identification of a character even if the character were poorly printed, had parts missing, or was partly covered by "dirt".
