  • comparing a first connected-component object from an image to a first plurality of numeral templates, wherein said first plurality of numeral templates corresponds to a first orientation;

    incrementing a first match counter, wherein said first match counter is associated with said first orientation, when said comparing a first connected-component object to a first plurality of numeral templates indicates a match between said first connected-component object and at least one numeral template of said first plurality of numeral templates;

    comparing said first connected-component object to a second plurality of numeral templates, wherein said second plurality of numeral templates corresponds to a second orientation;

    incrementing a second match counter, wherein said second match counter is associated with said second orientation, when said comparing said first connected-component object to a second plurality of numeral templates indicates a match between said first connected-component object and at least one numeral template of said second plurality of numeral templates; and
