Abstract
A method for reducing an image of a character or word string to one or more one dimensional signals, including the steps of determining page orientation, isolating character strings from adjacent character strings, establishing a set of references with respect to which measurements about the character string may be made, and deriving a plurality of measurements with respect to the references in terms of a single variable signal, from which information about the symbol string may be derived.
