1. A method for recognizing a graphical symbol such as a character comprising:

  • (a) obtaining a digitized image which includes as a portion thereof said graphical symbol which is a character of an arbitrary height from a predetermined set of characters comprising a predetermined font;

    (b) sampling at least that portion of the digitized image which contains said graphical symbol thereby creating a plurality of sample points at locations within the digitized image representing said graphical symbol;

    (c) displaying said plurality of sample points;

    (d) storing said plurality of sample points and their said locations within said digitized image, whereby said stored points and said locations are used to recognize said graphical symbol; and

    (e) performing a vector correlation on said stored points and locations which compares said points with a set of known points from a known graphical symbol comprising a known character from said font to determine if said graphical symbol matches said known character; and

    (f) using said vector correlation to determine a single correlation point for each graphical symbol.
